Eu3+-doped LaOF oxyfluoride thin films were prepared by the sol-gel method using trifluoroacetic acid as the fluorine source. The photoluminescent properties of the films depended on the heating temperature as well as the Eu3+ concentration. The optimum concentration of Eu3+ for the strong visible emission at 611 nm was shown to be 10 mol%.
