Subglobose YBO 3 :Ln 3? (Eu, Tb) phosphors have been successfully synthesized via a simple solutionbased hydrothermal method using Y 2 (CO 3 ) 3 (H 2 O) 2 colloid spheres as the precursor. The crystal structure, morphology, chemical composition and photoluminescence property of the phosphors were investigated by X-ray diffraction (XRD), transmission electron microscope, Fourier transform infrared (FTIR) spectroscopy and fluorescence spectrophotometer. The as-prepared phosphors present subglobose morphology and have a diameter of about 1 lm. XRD and FTIR results confirm that the vaterite-type YBO 3 can be synthesized by this method. The YBO 3 :Eu 3? exhibited strong orange emission at 591 nm and red emission at 610 nm, which were respectively ascribed to the ( 5 D 0 -7 F 1 ) and ( 5 D 0 -7 F 2 ) transitions of Eu 3? . The YBO 3 :Tb 3? showed dominant green emission at 542 nm due to the 5 D 4 -7 F 5 transition of Tb 3? .

Phosphor doped with erbium ion with variable concentration (0.5-2 mol%) was synthesized by solid state reaction method. CaY 2 O 4 :Er 3+ phosphor is characterized by X-ray diffraction technique for structural analysis and crystallite size calculation. Average crystallite size was found to be nearly 58 nm. Two prominent TL glow peaks found at 163 ∘ C associated with higher temperature peak 340 ∘ C. The peak intensity of higher temperature (340 ∘ C) peak was less as compared to lower temperature peak (163 ∘ C) because the deep trapping formation is less in case of UV irradiation. Sample shows good TL glow curve and for variable UV exposure time maximum TL intensity was found at 20 min UV exposure which is optimized UV exposure time. Sample was studied by photoluminescence emission spectra excited by xenon flash lamp with nearly 360 nm and four prominent peaks found at wavelengths 445, 525, 553, and 565 nm; here the 445 and 565 nm peak were intense as compared to others. From the PL emission spectra, it is concluded that the color tenability of prepared CaY 2 O 4 :Er 3+ was blue-green and it is verified by CIE coordinate. Kinetic parameters of prepared phosphor were calculated by computerized glow curve deconvolution (CGCD) technique.

ABSTRACTconcentration up to 0.4 mol% in Y 2 O 3 and thereafter it decreases with further increase of Er 3+ concentration. Also, the intensity of low temperature TL glow peak (~422 K) increases with increasing ion fluence up to 1×10 12 ions cm -2 and decreases with further increase of ion fluences. The TL trap parameters were calculated by glow curve shape method and the deconvoluted glows were exhibit of second order kinetics.
