摘要

A study was carried out on the luminescence excitation spectra and photoluminescence (PL) spectra as well as the luminescence kinetics of low-density polyethylene composites with different contents of CaGa₂S₄:Eu²⁺ phosphor filler. The phospholuminescence was attributed to the 4f⁶5d → 4f⁷ transition of the Eu³⁺ ion and was greatest when the filler concentration was 7 vol.%. The dependence of the PL intensity on the excitation power density up to 0.3 W/cm² was found to be linear, indicating that these phosphors can be used as visible radiation sources in various lighting systems.
