A series of nanocomposite (NC) powders and coatings of ZnO–GeO₂–TeO₂:xSm³⁺ glass and Y₃Al₅O₁₂:Ce³⁺ nanoparticles (YAG:Ce) are fabricated. Samarium ions concentration of the glass phosphor is varied with x values of 0.3, 1.0, 3.0, and 5.0 mol%. The powder batches are prepared with a 95/5 mass ratio of glass/YAG:Ce and uniaxially pressed to obtain powder pellets that are heat‐treated at 350 °C. Morphology and structural characterization are conducted through X‐ray diffraction analysis, scanning electron microscopy, and Raman spectroscopy. The photoluminescence properties of NCs are investigated under different wavelengths of 340, 403, and 460 nm, showing a global emission tonality in the reddish‐orange and yellowish‐green region according to the estimated CIE 1931 chromaticity coordinates. Also, NC coatings soda–lime glass slides are fabricated, and their photoluminescence is characterized using an UV light‐emitting chip (≈365 nm) and a blue light‐emitting chip (≈460 nm). The global emission under UV and blue light from the light‐emitting diode (LED) chips of the NC coatings shows a color tunability in the warm white light and yellowish‐green region.

Y3Al5O12：Ce3 +和Sm3 +掺杂的锌-锗酸盐-碲酸盐玻璃纳米复合粉体和涂料的颜色可调发射，用于发光二极管应用

制备了一系列纳米复合材料（NC）粉末和ZnO–GeO ₂ –TeO ₂：x Sm ³⁺玻璃和Y ₃ Al ₅ O ₁₂：Ce ³⁺纳米颗粒（YAG：Ce）的涂层。玻璃磷的离子浓度随x变化值为0.3、1.0、3.0和5.0摩尔％。以95/5的玻璃/ YAG：Ce的质量比制备粉末批料，并单轴压制以获得在350°C热处理的粉末粒料。形态和结构表征是通过X射线衍射分析，扫描电子显微镜和拉曼光谱进行的。在340、403和460 nm的不同波长下研究了NC的光致发光特性，根据估计的CIE 1931色度坐标，在红橙色和黄绿色区域显示了整体发射色调。此外，还制作了NC涂层钠钙玻璃载玻片，并使用UV发光芯片（≈365nm）和蓝色发光芯片（≈460nm）对它们的光致发光进行了表征。
