[EN] CaAl2O4:Eu3+ (1 mol.%) co-doped with varying concentration of Gd3+ (1, 2, 5, and 10 mol.%) were prepared by combustion synthesis method at 600 C and further annealed at 1000 ºC. All the compositions were investigated ...
[EN] BaAl2O4:Eu2(+)/Eu3(+) (1mol %) co-doped with varying concentrations of Gd3(+) (1, 2, 5 and 10mol%) were prepared by combustion synthesis method at 600 degrees C. All the compositions were investigated for their ...
[EN] Yb3þ doped ZnO/MgO nanocomposite were prepared by combustion synthesis method. The samples
were further heated to 1000 °C to improve their crystallinity and photoluminescent efficiency. The
concentrations of Yb3þ ...
. Ta2O5:Eu3+: Mg2+ or Ca2+ phosphor materials were prepared by molten salt method using KCl as flux. The Xray
diffraction (XRD) patterns illustrated that the well crystallized Ta2O5:Eu3+: Mg2+ or Ca2+ were formed in the ...
