phosphor were synthesized by high-temperature solid-phase method. Their structure characteristics
photoluminescence excitation and emission spectra
lifetime and temperature-dependent emission spectra have been discussed. The results show that the emission peaks of the sample are mainly located at 490 nm and 577 nm
and can produce uniform white light under the excitation of near-ultraviolet light/ultraviolet light. The concentration quenching mechanism has been investigated and demonstrated to be a dipole-dipole interaction. The thermal stability based on the temperature-dependent PL spectra of Cs
