Abstract
The luminescence spectral properties of La0.95Nd0.05MnO3 were investigated upon irradiation with a focused 808 nm CW (continuous wave) laser excitation. An anti-Stokes broadband emission in the visible range centered at 670 nm and a Stokes band in the infrared range centered around 2000 nm were recorded. Their intensities increased exponentially with excitation laser power. The mechanism of laser-induced emission is discussed in terms of an intervalence charge transfer mechanism involving the Mn3+–Mn4+ ionic pair.
