摘要

BaSr2(PO4) 2:4 %Eu3+, 4 %A (A = Li+, Na+, K+) phosphors were prepared by high-temperature solid-phase method. The crystal structure, photoluminescence properties, thermal stability, chromaticity coordinates, and fluorescence lifetime of the samples were investigated. The excitation and emission spectra of the samples are broadbands and the maximum peak of the emission spectrum is located at 619 nm. Among three charge compensators, the luminescence intensity is optimal for Li+ co-doping case, and the quenching temperature of the typical sample is about 500 K. the fluorescence lifetime τ $\left\langle \tau \right\rangle $ is 1469.6 ns, and the chromaticity coordinates exhibit a strong red emission. The present phosphor has a potential application for white light-emitting diodes (LEDs) under the near-ultra violet (n-UV) light excitation.

Red-emitting phosphors of BaSr2(PO4)2: 4 %Eu3+, 4 %A (A = Li+, Na+, K+) for white LEDs
Abstract BaSr2(PO4)2: 4 %Eu3+, 4 %A (A = Li+, Na+, K+) phosphors were prepared by high-temperature solid-phase method. The crystal structure, photoluminescence properties, thermal stability, chromaticity coordinates, and fluorescence lifetime of the samples were investigated. The excitation and emission spectra of the samples are broadbands and the maximum peak of the emission spectrum is located at 619 nm. Among three charge compensators, the luminescence intensity is optimal for Li+ co-doping case, and the quenching temperature of the typical sample is about 500 K. the fluorescence lifetime τ $\left\langle \tau \right\rangle $ is 1469.6 ns, and the chromaticity coordinates exhibit a strong red emission. The present phosphor has a potential application for white light-emitting diodes (LEDs) under the near-ultra violet (n-UV) light excitation.
