摘要：

A novel red phosphor, CaMoO4:Eu3+, has been developed for white light emitting diodes (LEDs). The phosphor was prepared by using oxides in air and its luminescent properties have been investigated. The excitation and emission spectra indicate that this phosphor can be effectively excited by ultraviolet (UV) (394 nm) and blue (464 nm) light, and exhibits a satisfactory red performance (616 nm), nicely fitting, in with the widely applied UV or blue LED chips. The novel phosphor is much more stable and has stronger emission intensity than the sulfide red phosphors used in white LEDs. (C) 2004 Elsevier B.V. All rights reserved.
