A phosphor-in-glass (PiG) with red and green phosphors using Nd-doped glass as a host matrix was fabricated to produce a white light emitting diode (wLED) with a wide color gamut. The LuAlO:Ce and CaAlSiN:Eu contents were adjusted to achieve white emission for liquid crystal display (LCD) applications. The silicate glass was doped with varying concentrations of NdO to modify the photoluminescence spectra of the wLED, by the hypersensitive absorption of the Nd:I4→G4,G2 transition. The color coordination, the color rendering index, and the color co-related temperature of the PiG-mounted LEDs were modified by the introduction of Nd. The color gamut of the wLED was monitored and found to have effectively improved with the Nd-doped silicate glass.
制备了一种以掺钕玻璃为基质、含有红色和绿色荧光粉的玻璃中荧光粉（PiG），以生产具有宽色域的白光发光二极管（wLED）。调整了LuAlO:Ce和CaAlSiN:Eu的含量，以实现用于液晶显示器（LCD）应用的白色发射。通过Nd:I4→G4、G2跃迁的超灵敏吸收，向硅酸盐玻璃中掺杂不同浓度的NdO，以改变wLED的光致发光光谱。通过引入Nd，对安装有PiG的LED的色坐标、显色指数和色相关温度进行了修正。监测了wLED的色域，发现掺Nd硅酸盐玻璃有效地提高了其色域。
