Ca2MgTeO6∶Bi3+,Mn4+荧光粉具有不同温度敏感性的双发射中心,分别来自于Bi3+离子3P1 →1S0跃迁和Mn4+离子的2E g →4A2g跃迁。由于Bi3+、Mn4+离子的发光强度随温度变化的规律不同,利用该特性进行测温研究,在200~500 K范围内,该荧光粉的最大绝对灵敏度和相对灵敏度分别达到0.027 K-1和1.83%·K-1,...
你好，想问下您找到什么解决方法了吗，我这边也在找无机物的cif文件。太难了。。。
Novel Sm-doped double perovskite Ca2MgTeO6 orange-red emitting phosphors were prepared using solid-state reaction at 1100 掳C. The powder phase purity, particle morphology and size, elemental composition, and luminescence properties of prepared samples were analyzed in detail. Under the 405 nm ...
Ca2MgTeO6Dy3+,Na+ phosphors are located in the yellow region.White light-emitting diodes (w-LEDs) were fabricated with a high color rendering index (Ra) of 88 and a good correlated color temperature (CCT) of 5440 K.All observed properties indicate that Ca2MgTeO6:Dy3+,Na+ phosphors ...
