摘要: White light-emitting diodes (LEDs) for green lighting are new solutions energy saving and environmental protection. Ca3SiO4Cl2:Ce,Eu is an efficient phosphor white LEDs. Effective transfer from Ce3+ to Eu2+ occurs in due good spectrum overlap between the emission band of Ca3SiO4Cl2:Ce excitation Ca3SiO4Cl2:Eu, hues vary systematically blue at different Ce concentrations. A great improvement luminescent property Ca3SiO4Cl2:Eu has been observed on doping, which attributed increase number centers (Eu2+) doping. The optimal sample a quantum efficiency up 75%, can be Copyright © 2014 John Wiley & Sons, Ltd.
