Abstract

The photoluminescence low-temperature studies results for nanoscale tin dioxide films obtained by a sol-gel method using polymers are presented. The SnO2 films exhibited photoluminescence at room temperature in the orange-red spectral region (1.85–1.9 eV and 2.32 eV). In the interval 9–300 K, the temperature dependences of the peaks’ energy intensity and half-width are considered. The form of these dependences is explained by the temperature quenching of luminescence on donor-acceptor pairs and the participation of phonons in the light emission process.
