Ca1-2xEuxLixMoO4:: A novel red phosphor for solid-state lighting based on a GaN LED

A novel red phosphor Ca1-2xEuxLixMoO4 with high performance is reported. Under the excitation of 254 nm UV light, its, luminescent intensity is comparable to that of the commercial red phosphor Y2O3:Eu3+. With high Eu3+ concentration, the phosphor has strong excitation due to f-f transitions of Eu3+ appearing around 395 nm. Thus, it is a promising material for solid-state lighting based on GaN light-emitting diode (LED). (c) 2005 The Electrochemical Society. [DOI: 10.1149/1.1856924] All rights reserved.
