Abstract: Highly oriented perovskite manganite (La0.55Er0.05Ca0.4MnO3) thin films were deposited on silicon (1 0 0) substrates by magnetron sputtering. Photoluminescence of Er3+ at around λ = 1.53 μm has been detected at room temperature when excited by a continuous wave Nd-YAG laser at 1.064 μm. The photoluminescence intensity is proportional to the excitation laser intensity. Based on optical absorption measurements, the energy transfer from the manganese ion to the erbium ion is proposed as the likely mechanism contributing to the observed photoluminescence of Er3+.
