Abstract
In the 5–100 K temperature range, the photoluminescence spectra of poly(methylphenyl)silane (PMPS) and polystyrene films doped with acetophenone, propiophenone, benzophenone, diphenyl, and naphthalene, as well as the thermostimulated luminescence spectra of neat PMPS films, have been investigated. It has been shown that the PMPS film phosphorescence spectrum consists of a structureless band with a maximum near 450 nm, and the literature structural phosphorescence spectrum of this polymer may belong to an uncontrolled impurity or a defect with chromophore groups of acetophenone.
