AbstractTwo new selenides with diamond-like structures, Li7Cd4.5Ge4Se16 and Li6.4Cd4.8Sn4Se16, were synthesized by using a conventional high-temperature solid-state reaction method. They crystallize in the space group Pna2(1) (no.33) of the orthorhombic system. Their three-dimensional frameworks consist of corner-sharing LiSe4, CdSe4, and MSe4 (M=Ge, Sn) tetrahedra. These two compounds exhibit strong powder second-harmonic generation responses that are about 1.2 and 2.5times that of the benchmark AgGaS2 at a laser wavelength of =2.09m, and also demonstrate typeI phase-matchable behavior. The optical bandgaps were determined to be 2.18 and 1.95eV for Li7Cd4.5Ge4Se16 and Li6.4Cd4.8Sn4Se16, respectively. Furthermore, these two materials exhibit congruent melting behavior at rather low temperatures of 985 and 1060K, respectively, which makes bulk single crystal growth by using the Bridgman-Stockbarger method possible. Our study indicates that these two materials show advantages over the traditional IR NLO material CdSe and are promising for practical applications.
