Abstract

New photochromic glasses in the system AlCdOF, AlCdPbOF and AlCdPbO were obtained. 27Al nuclear magnetic resonance spectra confirmed that both Al(4) tetrahedra and Al(6) octahedra coexisted in the glasses containing fluoride ions and the number of the latter increased, accompanied by an increase of the fraction of AlF bonds, with increasing atomic ratio F/O. However, most fluorine is coordinated with the Al(6) octahedra. Photo-induced absorption decayed slowly, accompanied by luminescence, and its half-life period was about 10 h at room temperature in the dark. The possible color centers are discussed on the basis of electron spin resonance spectra.
