Approach for quality deep-ultraviolet nonlinear optical crystals via a substitution strategy of channel species in zeolite

Abstract

Exploring the connections between the ion substitution of a material, its crystal structure, and its performance in applications is a regular task in synthetic chemistry. However, there still remain major challenges in the substitution of polyanionic groups for single ions. Herein, a strategy of channel species substitution of single anions by polyanionic groups in a zeotype rigid framework to design a new deep-ultraviolet nonlinear zincophosphate, {[Li₃Na₃(SiF₆)]Cs₂}[(ZnPO₄)₆], and tune physicochemical properties was proposed.
