Abstract

Amorphous Eu₂O₃ was prepared by an aqueous sol-gel method. Emission due to the ⁵D₀ →⁷F_J (J = 0, 1, 2) transitions of Eu³⁺ ions were observed. The dominant transition was the ⁵D₀ →⁷F₂ red emission of Eu³⁺. The properties of the as-prepared samples were different with changes in the annealing temperature. To investigate the luminescence properties of the amorphous Eu₂O₃, the temperature-dependent photoluminescence (PL) spectra of samples annealed at 600 °C were measured in the temperature range 77-300 K. PL peak positions were unchanged with the change of temperature.
