Temperature dependence of luminescence emission from cerium- and europiumdoped MgO is reported. The emission intensity changes with increase in the phosphor temperature. The phosphor showed peaks in the brightness-temperature curves. The intensities at static temperatures were always lower, indicating that temperature quenching occurs in almost all cases. The same is also evident from spectral distribution curves obtained at different temperatures.
