PbTe nanocrystals have been grown in doped glasses. By choosing the appropriate glass matrix and controlling the heat treatment temperatures and times, the quantum confined energy gaps of the PbTe dots can be changed in the wavelength range 1.1 – 2.0 µm. These glasses are potential materials for applications in optical communication and optoelectronic devices.
