Enhanced Photoluminescence Properties of Li/Al-doped YPO4:Eu Phosphors
Different concentrations of Li/Al-doped YPO4:Eu0.05 phosphors have been prepared by the solid state reaction method and are characterized by X-ray diffraction, scanning electron microscopy, excitation and emission measurements. The dependence of various optical and morphological properties of the prepared materials on Li/Al concentration has been discussed in our present work. Incorporation of ...

متن کاملSynthesis and photoluminescence properties of layered oxides intercalated with Eu3+ ions by electrostatic self-assembly method using oxide nanosheets
Layered oxides intercalated with Eu ions were prepared by self-assembly deposition method based on the electrostatic interaction between negative charged oxide nanosheets and Eu ions. The layered oxides were composed of two-dimensional host nanosheet layer with guest Eu ions and gave Eu emission based on an energy transfer from bandgap excitation of the host oxide nanosheets to the Eu ions. The...
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...
متن کاملEnhanced photoluminescence in CaMoO4:Eu3+ by Gd3+ co-doping.
We have studied the luminescence property of CaMoO4:Eu(3+). The emission peaks at 590 ((5)D0→(7)F1) and 613 nm ((5)D0→(7)F2) for Eu(3+) are observed after excitation at 266 nm (i.e. Mo-O charge transfer band). The peak intensity of the latter dominates over the former indicating an asymmetric environment of Eu(3+) in EuO8 polyhedron or parity mixing. Luminescence intensity increases significant...
