A remote color converter with a phosphor in silicone (PiS) structure was fabricated using CsPbBr₃ perovskite nanocrystal embedded glass (PNEG) as a green phosphor. When the PNEG was pasted on a glass substrate and mounted on a blue LED, it showed enhanced thermal and photo stability compared with the bulk PNEG. The remote color converter was used to prepare a white LED, which had a wide color gamut of up to 130% of the National Television Standards Committee (NTSC) defined area with the addition of K₂SiF₆:Mn⁴⁺ (KSF:Mn⁴⁺) as a red phosphor. The feasibility of a flexible remote white color converter using ultra-thin glass (UTG) as a substrate was examined and discussed.

基于超薄玻璃和 CsPbBr3 钙钛矿纳米晶嵌入玻璃的柔性远程荧光粉颜色转换器，用于宽色域白光 LED

使用 CsPbBr ₃钙钛矿纳米晶体嵌入玻璃 (PNEG) 作为绿色荧光粉，制造了具有硅胶荧光粉 (PiS) 结构的远程颜色转换器。当 PNEG 粘贴在玻璃基板上并安装在蓝色 LED 上时，与块状 PNEG 相比，它显示出增强的热稳定性和光稳定性。远程颜色转换器用于制备白色 LED，其色域宽达国家电视标准委员会 (NTSC) 定义区域的 130%，并添加了 K ₂ SiF ₆ :Mn ⁴⁺ (KSF:Mn ⁴⁺ ) 作为红色荧光粉。研究和讨论了使用超薄玻璃 (UTG) 作为基板的柔性远程白色转换器的可行性。
