Glasses doped with Cu20 microctrystallites in diameter of 15-100nm were prepared by an ion-exchange method using soda-lime-silicate glass substrates and copper containing paste. The size and the concentration of Cu20 microcrystallites in glasses increased with increasing ion-exchange temperature and duration. The optical absorption ascribed to the excitons of Cu20 and the optical effect due to the exciton confinement in Cu20 microcrystallite were observed.
