The positron annihilation lifetime spectroscopic technique was applied to study nanocrystals formation during controlled crystallization of a chalcogenide glass 51GeS 2 -9Sb 2 S 3 -40PbS, which was thermally treated at 330 Β°C for up to 15 h. The technique provided valuable information for in depth u
