Defect-linked absorption and luminescence had been exposed and a means to decrease them was prompt. The electronic composition, density of states, and many optical Houses have been calculated from the initial principles for Li2In2GeSe6. Calculated nonlinear coefficients and rather substantial birefringence show a solid period-matching capacity. These investigations demonstrate that Li2In2GeSe6 is usually a promising mid-infrared nonlinear optical crystal.
Preliminary experiments have indicated that this stoichiometry-dependent mid-IR absorption in AgGaSe(two) crystals can be substantially lowered by optimization of the method parameters all through crystal growth and annealing.
