We have studied the origin of the strong visible photoluminescence of nanometer-size Ge crystal lites in SiO2 glassy matrix. Spectroscopic analyses and electron microscopic studies show that the room-temperature visible photoluminescence comes from Ge crystallites of diameter of 4 nm or less. The structure of Ge crystallites of diameter of 4 nm or less differs from the diamond structure.
