Enhancement of second harmonic generation, optical and dielectric properties in L-asparagine monohydrate single crystals due to an improvement in crystalline perfection by annealing

Significant improvement of crystalline perfection in L-asparagine monohydrate single crystals was achieved by annealing. As a result of the improvement in crystalline perfection, remarkable enhancement in second harmonic generation efficiency, optical transparency, fluorescence intensity and dielectric properties was observed.
