Internal energy transfer phenomenon and light-emission properties of γ-LiAlO2 phosphor doped with Mn2+

摘要: γ-LiAlO2:Mn2+ phosphor was synthesized using the cellulose-citric acid sol-gel method, and its light emission and energy transfer properties were investigated. Excitation and emission spectrum analysis revealed a decrease in intensity of the spectrum as the amount of Mn2+ doping increased. Blasse’s equation determined the maximum distance for energy transfer between Mn2+ ions as 4.3142 nm. Dexter’s theory verifies that the mechanism of energy transfer between Mn2+ ions conforms to an electric dipole and electric quadrupole interaction.
