Abstract
The photoluminescence (T=5 K) and absorption (T=295 K) spectra and thermostimulated luminescence (T=5–300 K) curves of poly(methylphenyl)silane (PMPS) films are investigated as functions of the film thickness, annealing temperature, and oxygen content in air. It is revealed that the optical spectra and thermostimulated luminescence curves of PMPS films prepared in air at room temperature undergo changes after annealing at T=370–450 K. The assumption is made that the observed changes are associated with the formation of long polymer chain segments with a closer packing. This leads to an increase in the density of low-energy states of excitons and charge carriers. It is demonstrated that atmospheric oxygen substantially affects the formation processes and the energy disorder in the films prepared. The PMPS films are found to degrade after heating to T≥500 K.
