Enhanced photoluminescence of GdPO4:Tb3+ under VUV excitation by controlling ZnO content and annealing temperature

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].…”

Enhanced photoluminescence of Gd0.94(P1−xVx)O4:Eu0.06 red-emitting (0 ≤ x ≤ 1.0) phosphors

“…Second, the reduction of emission intensity for high V 5þ contents is caused by the poor powder characteristics, i.e., highly agglomerated and irregular morphologies, as discussed in Fig. 2 [35,36].…”

“…Park and Heo [36] synthesized (Gd 0.85Àx Zn x )PO 4 :0.15Tb 3þ (0 x 0.06) powders by ultrasonic spray pyrolysis. Subsequently, the effect of Zn 2þ content and annealing temperature on the PL properties of the (Gd 0.85Àx Zn x )PO 4 :0.15Tb 3þ phosphors annealed at 800e1100 C was investigated.…”

Facile synthesis and luminescence of GdPO4:Eu hollow microspheres by a sacrificial template route

“…Among the different kinds of rare earth orthophosphates, gadolinium orthophosphate has been shown to be an efficient host lattice for activator ions, which have become a research focus because of their important role in the field of light display systems, lasers, and optoelectronic devices, and medical and biological labels [9,10]. A lot of effort has been devoted to the chemical synthesis of REPO 4 nano/microstructures, including hydrothermal, solvothermal, ultrasonic spray pyrolysis and coprecipitation [11][12][13][14][15]. By combining the magnetic property of the matrix (GdPO 4 ) and the fluorescence property of the doping ions (Eu 3 þ ), multifunctional particles can be tailored.…”
