A new red luminescent powder and a method for making red luminescent ceramics

A new red luminescent powder is composed of BEiyQia8_x_yZnxTi03:aPr3+, bLu3+, cNa+ and dB3+, with titanate as the substrate, Pr3+ as the activator and Lu3+ as the sensitizer. The luminous powder is used to prepare the luminous red ceramics. The best known green luminescent powder is SrAl2O4 = Eu2+ and Dy3+, while the blue luminescent powder is SrAl2O4 = Eu2+ and Nd3+. The chemical properties, afterglow intensity and attenuation time of these two luminescent powder are similar. But there is no [...]
