High-efficient Tb 3+ activated SrAl 2 O 4 phosphor was synthesized by a combined combustion–solid-state reaction method. The precursor of SrAl 2 O 4 :Tb 3+ phosphor was prepared via a combustion process, and then the as-prepared powder was heated in a reductive ambient of activated carbon at 1250 °C for 1 h. The results of X-ray diffraction, scanning...
The well crystalline YAG:Ce 3+ phosphor was synthesized by solid-state method, and the temperature dependence of excitation and emission spectra of YAG:Ce 3+ phosphor were investigated in the temperature range from room temperature to 573 K. With temperature increasing, it was noted that the emission intensity of as-prepared phosphors decreased considerably more rapidly when pumped...
