“…The bulk properties of Sn-doped soda-lime glasses have been studied by Krohn et al [5] and Ziemath et al [6]. Krohn et al [5] reported an increase in elastic modulus with increasing Sn concentration, but with a different effect for SnO and SnO 2 doping, and showed that this was consistent with the predictions of a model developed by Makishima and Mackenzie [26].…”

Ziemath et al [6] found an increase in hardness with increasing SnO 2 concentration and also an increase in density. Both these studies suggested empirical linear relations to predict the influence of tin doping on the properties of bulk glass.…”

We have combined nanoindentation with measurements of Rayleigh wave velocity to determine the elastic properties of the surfaces of a commercial soda-lime float glass and found significant differences between the mechanical behaviour of the side in contact with the air and that in contact with tin. By using two measurement methods we have obtained the two independent elastic constants of glass (assuming surface isotropy and homogeneity). The air-side has a Young's modulus E = 81.3 ± 0.5 GPa and Poisson's ratio m = 0.22 ± 0.01, which is significantly different from the tin-side values of E = 79.6 ± 1.0 GPa and m = 0.187 ± 0.015. The Young's modulus of both surfaces is significantly greater than the bulk value reported by the manufacturer of 73 GPa and Poisson's ratio smaller than the reported value of 0.23. The tin-side, having a lower Young's modulus than the air-side, is in the opposite sense to the reported increase in stiffness of bulk float glass with increasing levels of tin doping. We critically review the possible mechanisms for the difference in mechanical properties between the tin-and air-sides of a float glass sheet and produce quantified predictions of likely changes from each mechanism. From this we conclude that no individual mechanism can account for the magnitude of the difference we have measured.

“…Ziemath et al have reported the absorption in visible region for Sn-including silicate-system glasses and have attributed the absorption to formation of colloidal SnO 2 particles in the glass. 20) Figure 3 shows the PL spectra in SZB glasses excited at different photon-energies. In the SZB1100, a broad PL band at ³2.8 eV, which corresponds to blue-PL due to the s 2 sp transition of Sn 2+ , was detected [ Fig.…”

We prepared SnOZnOB 2 O 3 system glasses by means of melt-quenching technique with different melting-process temperatures in range of 11001500°C, and examined the impact of the process temperature on photoluminescent (PL) property. The glass obtained at 1100°C showed clear PL band at ³2.8 eV at room temperature. As elevating the process temperature, a shoulder appeared at lower-energy side of the PL band, and eventually broad band with peak at ³2.2 eV developed, resulting the clear orange PL. We demonstrated that the PL-color is controllable from blue to orange via white by change in the process temperature.©2015 The Ceramic Society of Japan.

Basically, phosphor powder is synthesized by addition of emissive ions based on ff and/or fd transition into host crystal, and is used in fluorescent lamp, plasma display and so on. Recently, PL-color tuning has a significant importance in phosphor material in terms of the variety of PL-color and color rendering for white-LED. In order to achieve them, co-and tri-doping of rare-earth (RE)/transition-metal ions has been considered. 1)3) Glass material has high optical transparency and shape-imparting on the basis of random structure, which allows the material to acquire the practical and engineering usages. Furthermore, since glass material is prepared through the mixing process of startingmaterials, e.g., glass-former and glass-modifier, and subsequent melting-process, it is quite suitable for mass-production. Therefore, photoluminescent (PL) property of oxide-glasses is examined extensively to apply them to phosphor material. 4)11)If once composition of glass is decided, the network-structure and physical property are settled in principle. Nevertheless, researcher experimentally knows that some properties of glass largely depends on the synthesis environment/condition. For example, the melting-process temperature significantly affects the crystallization, coloration and defect structure.12)14) This leads us to expect that the process temperature also affects the PL property. The process temperature is an easily-variable parameter in glass synthesis. Therefore, in this study we examined the effect of melting-process temperature on PL property in emissive glass material aiming to control the PL-color without any RE-doping.SnO-containing glass has absorbed much attention because the glass possess a large quantum-yield (QY) for visible blue-PL caused by T 1 S 0 relaxation based on s and consequently SnO-containing glass is regarded as a possible candidate for RE-free phosphor and scintillator material. 8),16) In addition, glass in ZnOB 2 O 3 system, which consists of a typical strong former, is frequently studied from optical/spectroscopic point of view. 17),18) Therefore, nominal composition of test glass in this study was determined to b...

“…Si oxide can serve as a chemically protective film on the surface in order to improve the chemical durability of the nano-compound and is coated onto the nano-compound using water-glass hydrolysis. Since Si is an oxide, we significantly modified the surface of the SiO 2 film material which was employed in this study [11,12]. Ceria (CeO 2 ) has been widely used as a solid ion conductor and as a catalyst carrier, as it is a heat resistant material with a high melting temperature of 2477°C.…”

The purpose of this work was to the application of Si oxide coatings. This study deals with the preparation of ceria(CeO 2 ) nanoparticles coating with SiO 2 by water glass and hydrolysis reaction. First, the low temperature hydro-reactions were carried out at 30~100°C. Second, Silicon oxide-coated Nano compounds were obtained by the catalyzing synthesis. CeO 2 Nano-powders have been successfully synthesized by means of the hydrothermal method, in a low temperature range of 100~200°C. In order to investigate the structure and morphology of the Nano-powders, scanning electron microscopy(SEM) and X-ray diffraction(XRD) were employed. The XRD results revealed the amorphous nature of silica nanoparticles. To analyze the quantity and properties of the compounds coated with Si oxide, transmission electron microscopy(TEM) in conjunction with electron dispersive spectroscopy was used. Finally, it is suggested that the simple growth process is more favorable mechanism than the solution/aggregation process.
