“…Figure 3a shows the energy dispersive peak of Si at approximately 1.9 eV which could not be distinguished because of the Sr peak, which is consistent with that of reported literature [27]. A detailed analysis of the EDS results showed that the relative content of Si distributed on the surface of luminescent particles was about 4.43%.…”

“…As shown in Figure 2a, the absorption bands peaked at 850, 770, and 642 cm −1 for SAOED are attributed to the stretching vibration modes of SrAl 2 O 4 [27]. These corresponding characteristic peaks of SrAl 2 O 4 can also be seen for SiO 2 @SAOED and NH 2 @SiO 2 @SAOED phosphors, indicating that the main structure of the SAOED phosphors was not affected by SiO 2 and APTMS modification.…”

“…Up to date, several physical and chemical strategies have been used to improve the hydrolytic resistance of phosphors [22,23,24]. The importance of silicone oil [25] and SiO 2 coating layer [26,27] were confirmed in terms of enhancing the water resistance of phosphor particles. However, even though the water resistance of phosphors was significantly improved, these approaches did not address the problem of low surface activity of phosphors, especially in water-based systems containing cellulose.…”

Fabrication Flexible and Luminescent Nanofibrillated Cellulose Films with Modified SrAl2O4: Eu, Dy Phosphors via Nanoscale Silica and Aminosilane

Flexible 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO)-oxidized nanofibrillated cellulose (ONFC) films with long afterglow luminescence containing modified SrAl2O4: Eu2+, Dy3+ (SAOED) phosphors were fabricated by a template method. Tetraethyl orthosilicate (TEOS) and (3-aminopropyl) trimethoxy-silane (APTMS) were employed cooperatively to improve the water resistance and compatibility of the SAOED particles in the ONFC suspension. The structure and morphology after modification evidenced the formation of a superior SiO2 layer and coarse amino-compounds on the surface of the phosphors. Homogeneous dispersions containing ONFC and the modified phosphors were prepared and the interface of composite films containing the amino-modified particles showed a more closely packed structure and had less voids at the interface between the cellulose and luminescent particles than that of silica-modified phosphors. The emission spectra for luminescent films showed a slight blue shift (3.2 nm) at around 512 nm. Such flexible films with good luminescence, thermal resistance, and mechanical properties can find applications in fields like luminous flexible equipment, night indication, and portable logo or labels.

“…It could be clearly seen from Figure 4(A) that the pure SMSED phosphors had a rough surface with sharp edges, which was a typical characteristic of phosphors prepared by mechanical grinding. [ 26 ] Clearly, after modification with KH550, the surface of the SMSED phosphor was covered with a coating layer, and the KH550‐SMSED phosphors showed a smooth surface with blurred edges and corners (Figure 4(B)).

Combining wood plastic composites with 3D printing technology can easily manufacture parts with complex shapes and wood colors, but the single function limits their applications. In this research, Sr2MgSi2O7:Eu2+, Dy3+ phosphors/particleboard wood flour/poly (lactic acid) (SMSED/PWF/PLA) photoluminescence composites for 3D printing were successfully manufactured by melt extrusion. The water resistance and chemical structure of SMSED phosphors modified with five different types of silane coupling agents were characterized by water‐resistance test, Fourier transform infrared spectroscopy, and X‐ray diffraction. It was found that 3‐aminopropyltriethoxysilane (KH550) had the best effect on the modification of SMSED phosphors, formed a dense protective film. Afterward, the effect of KH550‐modified SMSED (KH550‐SMSED) phosphors content on the thermo‐mechanical properties of wood plastic composites was studied. The experimental results indicated that the mechanical properties and thermal stability of wood plastic composites were significantly improved, with the incorporation of KH550‐SMSED phosphors. Finally, based on SMSED/PWF/PLA composites and 3D printing technology, a safety warning model that could emit blue light in the dark and a small dinosaur artwork that could swing flexibly were prepared.

“…There are many ways to coat the phosphors, including sol-gel, chemical vapor deposition and homogeneous co-precipitation [4]. In this paper, sol-gel method was used to coat a TiO 2 layer on the surface of YAG phosphor with tetrabutyltitanate, anhydrous ethanol, distilled water and glacial acetic acid as raw materials.…”
