The effect of co-substitution of heterovalent ions Ga3+ and Sb5+ on nonlinear optical properties of phosphate crystals

“…27 However, single doping of NLO-active ions in KTP crystals can lead to difficulties in crystal growth, 28 and the NLO performance of the crystals will not be improved. 29 Therefore, we consider introducing the Ga element to balance charges, as Ga 3+ , Sb 5+ and Ti 4+ ions have extremely similar ionic radius and are prone to substitution. In this study, we chose the Sb 5+ NLO-active ion with a d 10 electronic configuration and Ga 3+ ions for co-doping in a KTP crystal.…”
