摘要
-
White-light-emitting phosphors Dy3+-doped CaLaB7O13were synthesized by solid-state reaction, and their luminescent properties were characterized for the applications in white-light-diodes (W-LEDs). The obtained samples were initially investigated by X-ray powder diffraction, photoluminescence excitation and emission spectra, the Commission International de L'Eclairage (CIE) chromaticity coordinates, and thermally stable properties. Dy3+-doped CaLaB7O13phosphors emitted a blue emission band centered at 480 nm and a yellow one centered at 575 nm with CIE chromaticity coordinates of (0.325, 0.339) under the excitation of near-UV (NUV) LED chips at 365 nm. The electric dipole-dipole interaction was demonstrated to be the energy transfer mechanism in Dy3+-doped CaLaB7O13phosphors, and the critical distance of energy transfer between the Dy3+ions was estimated to be about 0.920 nm. The temperature-dependent spectra imply Dy3+-doped CaLaB7O13show small thermal quenching. The present work indicated that Dy3+-doped CaLaB7O13was a promising white-light-emitting phosphor excited by NUV LED. ? 2018 Elsevier Ltd
