“…In this case, highly dispersed tin seems to provide the presence of many condensation nuclei and the low total amount of gold will then prevent the formation of large gold particles (few nanometers). In the same way, nanocrystalline phases Cu y Sb 2−x (O, OH) 6−7 have been highlighted with cupper and Cu 2 O phases in ruby colored cuprous oxide glasses [25]. In our case, no alloy has been detected between gold and antimony and the stronger releasing of Sb compared to Au in our leaching tests favors the hypothesis of alloy absence.…”

Soda lime silicate oxide glasses are studied to perform coloration thanks to gold nanoparticles' crystallization. This precipitation is conducted by chemical reduction of gold ions with stannous or antimony oxides as reducing agents. A control of the rendered coloration between blank to red shades has been obtained using Sb 2 O 3 agent and appropriate thermal treatments. The glasses remain colorless while heating up to 450°C. Structural glasses evolution is studied by MAS NMR spectroscopy of 29 Si and 23 Na nuclei to investigate the silicate network polymerization change and the modification of sodium/oxygen bond length versus nucleation state and growth of Au nanoparticles. A clear decrease of the Q 2 species part is observed with nanoparticles growth confirmed by the evolution of chemical shift for 23 Na resonance. A slight network polymerization is then showed independently of the only thermal treatment. This structural change could be induced by the antimony oxidation and change towards higher coordinations. Finally, the glasses chemical durability has been studied by leaching tests and shows lower alteration for colored glass. The optical spectroscopy applied to colored glasses has given rise to plasmon resonance phenomena at around 600 nm which is the typical surface plasmon resonance of gold for a refractive medium index of 1.5, with a shift of the resonance towards the higher wavelengths with increasing thermal treatment temperature. This shift is modelized by Drude and MIE approaches and confirms the trend observed by UV-visible measurement with an increasing absorption at the SPR correlated to a typical Ostwald growth mechanism according to the increase of the annealing temperature.

“…[43] Furthermore, the peaks which occurred at 740 cm À1 arise from O-Sb symmetric stretching from Sb 2 O 3 . [43,44] From the results of the spectrum, the positions or intensities of overall peaks for the control sample and EVA filled with 10 wt% Sb 2 O 3 and 30 wt% DBDPE closely resembled each other, without generating any new chemical peaks. This confirms that the addition of Sb 2 O 3 and DBDPE in the EVA substance in this study was a physical combination.…”

A high near-infrared (NIR) reflective cooling compound with flame retardant characteristics was fabricated by incorporating antimony trioxide (Sb 2 O 3 ) and decabrominated diphenyl ethane (DBDPE) into ethylene-vinyl acetate copolymer (EVA). The solar reflectivity and cooling capacities of the control sample and EVA compounds with either Sb 2 O 3 or DBDPE, and EVA composites embedded with Sb 2 O 3 and DBDPE, were evaluated by ultraviolet-visible-near infrared analysis and temperature tests. The effect of Sb 2 O 3 and DBDPE on the flammability, thermal behavior, and mechanical properties of EVA copolymer were determined via the UL-94 burning test, limiting oxygen index (LOI), differential scanning calorimetry, thermogravimetric analysis, and tensile and tearing tests. Compared with the glass blank, EVA compound filled with 10 wt% Sb 2 O 3 and 30 wt% DBDPE showed a roughly 17.3 C and 38.0 C decrease during sunlight exposure and in indoors, respectively, accompanied by the maximum NIR reflectivity of 68.8% in all as-prepared blends. Moreover, this as-prepared compound met a UL-94 V-0 classification and reached a LOI value of 29.3%. Notably, the singular addition of either Sb 2 O 3 or DBDPE improved the cooling capability of EVA but rarely fulfilled the fire retardant demand. In contrast, the incorporation of Sb 2 O 3 and DBDPE improved the desirable cooling and flame retardant properties.

“…A distinct color to the host glass according to each of the copper species depends on its coordination geometry and electronic transitions between its specific energy levels. It is known that introduction of copper oxide (CuO) in glass batch imparts red color under reducing conditions (in the presence of reducing agent like SnCl 4 , SnO 2 , Sb 2 O 3 ) of melting [8][9]. The red color is attributed to the formation of metallic copper or cuprite nanocrystals.…”

The silicate glass was prepared using rice husk as the source of silica. The base glass formula is composed of SiO2 (from rice husk ash), Na2CO3, K2CO3, ZnO, H3BO3, CaO and Al2O3 or Al. CuO was used as the colorant in the glass matrix in the absence and presence of reducing agent. The color of the glass obtained was varied from dark blue to blue depending on the amount of CuO and reducing agent. The expansion coefficients of copper doped glass are in the range of 12.43 x 10-6 - 14.35 x 10-6 (°C-1) which is common for the silicate glass. The finger prints of the bond vibrations were studied using IR spectroscopy. While the oxidation state and the coordination information of the copper ion in the glass matrix were investigated using X-ray absorption spectroscopy. In the absence and presence of reducing agent, Cu+ and Cu2+ exist in the glass matrix. However, in the presence of reducing agent, the amount of Cu+ in the glass matrix is higher.
