Modification of structural, optical, thermal and mechanical properties of KDP crystals on the addition of Ni2+

Nonlinear optical materials are acquiring a new significance day by day with the advent of a large number of devices utilizing solid state laser sources. Owing to this technological application KDP having superior nonlinear optical property has been exploited for various applications. KDP crystals were grown from aqueous solutions added with Ni2+. SHG studies confirm that the title exhibits NLO property. The influence of doping Ni2+ on the structural, optical, thermal, NLO and mechanical properties has been studied in this present investigation. It is observed that addition of Ni2+ improves the optical, thermal and mechanical properties of the crystal.
