  • Abstract
    Effects of temperature on the luminescence of LiMgPO4 and β-Ca2SiO4 doped with Eu3+ and Eu2+ is presented. The short distance compensation of the Eu3+ in the Ca2+ sites in β-Ca2SiO4:Eu2+/Eu3+ and the long distance compensation of Eu3+ in the Mg2+ or other sites in LiMgPO4:Eu2+/Eu3+ is responsible for different temperature behaviour of the luminescence in both materials. The importance of the energy of the Fermi level is also discusses.
