For developing warm white light emitting diodes(WLEDs),it is essential to search for an efficient nonrare earth-based oxide red phosphor,particularly excitable by ultraviolet or blue rather than green lights.It,when combined with either UV or Blue LED chips,can,therefore,absorb partially the excitation lights,and convert into red without reabsorping the lights from the composite device,and eventually improve the device perception.
