Effect of LiCl on the Microstructure and Luminescence Properties of YVO4:Eu3+ and YBO3:Eu3+ Phosphors
In this investigation, Eu3+ doped YVO4 /YBO3 phosphors were synthesized individually by conventional solid state method at 1100 °C under atmosphere condition. Meanwhile, different amounts of LiClwere used as the flux compound to modify the morphology of the phosphor particles and also final luminescence properties. It was concluded that even small amounts of fluxes play a vital role in the grow...
متن کاملPhotoluminescence properties of Al3GdB4O12:Eu phosphors
An investigation is reported of the photoluminescence (PL) properties of Al3GdB4O12:Eu phosphors. Under vacuum ultraviolet excitation, Al3GdB4O12:Eu exhibited a bright red luminescence with CIE chromaticity coordinates of (0.643, 0.356) with a PL intensity of 60% of the sodium salicylate standard. The PL spectrum showed a ground state splitting pattern consistent with D3 symmetry. The PL excita...

متن کاملSynthesis of YVO4:Eu3+/YBO3Heteronanostructures with Enhanced Photoluminescence Properties
Novel YVO(4):Eu(3+)/YBO(3) core/shell heteronanostructures with different shell ratios (SRs) were successfully prepared by a facile two-step method. X-ray diffraction, transmission electron microscopy and X-ray photoelectron spectroscopy were used to characterize the heteronanostructures. Photoluminescence (PL) study reveals that PL efficiency of the YVO(4):Eu(3+) nanocrystals (cores) can be im...
