VUV photoluminescence of green-emitting GdPO4:Tb,M (M: Al, Zn) synthesized by ultrasonic spray pyrolysis

Effects of organic additives on morphology and luminescent properties of Eu3+-doped calcium molybdate red phosphors

“…10 3+ shows lower crystallinity, smaller particle size, and higher surface roughness, corresponding to weak PL emission intensities inevitably. Besides of the effect of crystallinity on particle size, the PL intensity can be enhanced by the increased interaction area with excitation light and the reduced loss connecting with the larger particle size [34,39,40].…”

Extensive tailoring of REPO4 and REVO4 crystallites via solution processing and luminescence

“…On the other hand, GdPO 4 is able to sensitize Ln 3+ luminescence through intra-4f 7 electronic transition of the host Gd 3+ ions, 91 and the visible-light emission of GdPO 4 :Tb under vacuum ultraviolet (VUV) excitation is promising for application in plasma display panels (PDPs). 92 Aside from the Ln 3+ content and codoping, the characteristics of the host lattice (phase structure, local coordination, crystallinity, particle shape/size/dimensionality, defect type/concentration) play vital roles in influencing the luminescence performance and dynamics (such as spectral features, emission color, the efficiency of energy transfer, QY, and the kinetics of excitation and fluorescence decay). As for REPO 4 , although the hydrated h-REPO 4 phase is inferior to t-REPO 4 for luminescence because of the quenching effect of molecular water, 11 the compound intrigues researchers because of its abundant crystallite shapes and its ability to maintain the original morphology after dehydration.…”
