Abstract
It is demonstrated that copper oxides (specifically cuprous oxide) play an important role in the photochromism of standard FKhS-7 glasses. The absorption spectra of the FKhS glasses are compared with the spectrum of glasses with microscopic cuprous oxide particles and the spectra of cuprous oxide deposited on various substrates. Solid-phase photochemical reactions in heterosystems are shown to be responsible for photochromism.
