dc.description.abstract | A full-color-emitting phosphor, CaYAl3O7:Pr3+,Ce3+ was synthesized through conventional solid-state reaction. The structural properties of the phosphor were analyzed by Rietveld refinement, maximum entropy method, and luminescent properties were analyzed by co-activating with different rare earth ions. Photoluminescence spectra on excitation with 450 nm source were dominated by green band at 490 nm originating from P-3(0)-> H-3(4) transition of Pr3+ ions and less intense band at 617 nm due to D-1(2)-> H-3(4) transition. On codoping with Ce3+, phosphor exhibits an additional broad band originating from 5d(1)-4f(1) (F-2(7/2) and F-2(5/2)) of Ce3+, centered at around 540 nm due to efficient energy transfer from Pr3+ levels to Ce3+ levels. With this emission property we recommend CaYAl3O7:Pr3+,Ce3+ as potential single-phase full-color-emitting phosphor for solid-state lighting applications. | - |
