Abstract
Thallium halide microcrystals were grown from water solutions in a porous m atrix obtained from alkali borosilicate glass by etching, and their absorpt ion and luminescence spectra were studied. Constraining the crystal size wa s found to affect the stability of some crystal modifications. The exciton radii were determined, and the dimensions of microcrystals in which size qu antization effects become observable were estimated from the absorption spe ctra of bulk TlBr and TlCl crystals.
