Strong nonlinear optical effect attained by atom-response-theory aided design in the Na2MIIM IV2Q6 (MII = Zn, Cd; MIV = Ge, Sn; Q = S, Se) chalcogenide system†‡
Abstract
Two new phases, Na2MSn2Se6 (M = Zn/Cd), exhibiting overall high quality parameters for infrared nonlinear optical applications were synthesized based on a new atom response theory aided searching approach.
