Controlled peak wavelength shift of Ca1-xSrx(SySe1-y): Eu2+ phosphor for LED application

摘要

The highly efficient red-orange-yellow-emitting phosphor (Ca1-xSrx)(S1-ySey):Eu2+ in combination with commercial green phosphor SrGa2S4:Eu2+ and blue LED are proposed for a three-band white LED. The luminescence mechanism and optimization parameters are discussed on the basis of proposed peak wavelength diagram. (c) 2006 Elsevier Inc. All rights reserved.
