摘要: The infrared (IR) transmitting nanocrystallized chalcogenide glass only containing α-CdGa2S4 IR nonlinear optical crystallites, which were confirmed by x-ray diffraction and Raman scattering measurements, was fabricated through the controllable nucleation crystallization of with composition 82GeS2∙18CdGa2S4 at a temperature 325°C far below transition (Tg:415°C) for long duration. A clear second harmonic generation (green light, 532nm) could be observed in transparent glass, demonstrating frequency-doubling function prepared composite material.
