Intense luminescence of amorphous Eu2O3 prepared by aqueous sol–gel method
Source abstract
Abstract
Abstract Amorphous Eu2O3 was prepared by an aqueous sol–gel method. Emission due to the 5D0 → 7FJ (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.
