Two new polymorphism of BaGa4S7 was successfully discovered and synthesized. Among them, β-BaGa4S7 exhibits the best balance among a large phase-matching SHG response and a wide band gap, as well as the stable physicochemical property.

My research interests
|Key words: nonlinear optical crystals, solid state chemistry, crystal growth|
|Nonlinear optical (NLO) crystals—the unique materials capable of generating coherent radiation at various difficult-to-access wavelengths through frequency conversion technologies—are of particular importance for laser and photonic technologies. Currently, the commercial NLO crystals are mainly used in the ultraviolet (UV) and visible regions. However, in the deep-UV (λ < 200 nm) and mid-IR (3 μm < λ < 20 μm) regions, the available NLO crystals are still limited. Therefore, my research interests are to design, synthesize and grow new NLO crystals for the laser output in deep-UV and IR regions. The materials classes I am interested in include borates, phosphates, chalcogenides and some heteroanionic compounds, etc.|
