The photoluminescent properties of epitaxial Er doped BaTiO3films have been measured over the temperature range of 15 −295 K. The characteristic Er3+emission peak energy is centered at 0.800 eV and is nearly temperature independent. The integrated peak intensity at 295 K is comparable to the intensity at 15 K. The photoluminescence decay time is 6 msec. which is comparable to what is observed in other Er doped solids. The predicted laser gain is of the order of 10 cm−1.
