Abstract
- Efficient orange-emitting SmxY1−xSr2SbO6 phosphors, which can be excited by the UV light at 405 nm and hence emit bright orange light, have been successfully prepared by the traditional high-temperature solid-state method. The phosphors were characterized by X-ray diffraction patterns, SEM, photoluminescence spectra, diffuse reflectance spectra, temperature-dependent luminescence spectra and decay properties in detail. The optimum doping concentration and critical energy transfer distance of SmxY1−xSr2SbO6 were determined from the photoluminescence spectra of as-prepared samples with different Sm3+ ions. The good thermal stability of SmxY1−xSr2SbO6 was also illustrated by temperature-dependent spectra of the SmxY1−xSr2SbO6 phosphors at temperature from 293 to 453 K. These merits demonstrated that SmxY1−xSr2SbO6 could be a potential candidate as an orange-emitting component applied in phosphor-converted warm WLED. [ABSTRACT FROM AUTHOR]
