Abstract

The Bi₂S₃ microcrystallite doped thin films and glass lumps have been successfully prepared by the sol-gel process, the size of the microcrystallite in glass heated for different times at 400 degree(s)C was decided by the method of HRTEM. The optical transmission valley shifted towards longer wavelengths with longer heat-treatment time at 500 degree(s)C in the Bi₂S₃ doped thin films, showing the experimental evidence of quantum size effects. The red-shift of emission peaks in luminescence spectrum excited with longer wavelength is attributed to the broad distribution of particle size in Bi₂S₃ doped glass. The nonlinear refractive index of the Bi₂S₃ quantum dots glass which is studied by the method of Z- scan gives n₂ equals 3.3089 X 10^-9 esu. The optical second generation (SHG) of the Bi₂S₃-doped glass also is observed using a Nd:YAG colliding mode locked laser.
