Sol-gel synthesis and luminescence properties of CaGd2(MoO4)(4):Pr3+ phosphors for white LED applications
A series of novel red emitting CaGd2(MoO4)4:xPr3+ (x = 0.005–0.045) micro phosphors were successfully prepared via a simple citrate assisted sol–gel method-ray powder diffraction, scanning electron microscope, photoluminescence spectra and decay life time measurement were utilized to study the prope...
