Li+-doped Gd2O3:Eu3+ phosphors have been studied as potential red phosphors for application to field emission displays. The Li+-doped and undoped Gd2O3:Eu3+ phosphors were synthesized by low temperature solution combustion method. The enhanced luminescence was regarded as the result of the creation of oxygen vacancies due to the Gd3+ sites occupied by Li+ ions, the alteration of the crystal field surrounding the activator Eu3+ ions owing to the incorporation of Li+ into interstial sites. The result in a remarkable increase on photoluminescence and the strong emission was observed at 612 nm by a factor of 4.1 in comparison with that of undoped sample.
