摘要: A deep red phosphor AgLaMo 2 O 8 :Pr 3+ has been prepared by a conventional solid-state reaction technique. The effects of synthesis temperature and Pr -doped concentration on the luminescent properties crystal structures compound have investigated. Its excitation wavelength ranging from 440 to 500 nm fits well with characteristical emission commercial blue light-emitting diode (LED) chips. photoluminescence spectra exhibit emissions, strongest peak at 649 nm, show high color purity point (0.685, 0.315). Due its good performance, may be promising candidate for white LEDs.
