利用溴化鉀作為助熔劑，成功地於高溫爐合成出具有非中心對稱骨架結構的鋇金屬硫氧化物，此化合物的能隙高達3.75 eV，並具有良好的光致放光行為。其結構骨架是由GaO4 與GaSO3 四面體以共用角方式相互鍵結形成。沿c 軸方向延伸構成三維的六角柱結構，團簇結構的排列朝著特定的方向。
鋇金屬硫氧化物的通光範圍為2.5 μm – 12.5 μm，在紅外光區有良好的穿透度，加上具備寬能隙的優勢，意味著我們化合物有作為紅外非線性光學材料的潛力。不僅如此，在螢光性質部分，室溫情況下以激發光波長325 nm 照射放出黃綠光，放射光波長落在542 nm，且具有非常高強度的放光特性。

A barium oxychalcogenide with noncentrosymmetric framework was synthesized using KBr flux in the high-temperature furnace. This compound has a wide band gap of 3.75 eV and exhibits good photoluminescence (PL) behavior. It is constructed by GaO4 and GaSO3 tetrahedral via corner-sharing. A three-dimensional hexagonal column along c axis and all the cluster arrange in a specific direction.
Both the optical transparence for the sample begin from infrared region 2.5–12.5 μm and the advantage of the wide band gap mean that this compound has the potential application as nonlinear optical (NLO) materials. In addition, the PL property of it is investigated at room temperature exhibits a strong emission band at 542 nm under excitation wavelength of 325 nm.
