硫化锌（化学式：ZnS）是锌的硫化物，为白色至黄色粉末或晶体，难溶于水，主要以闪锌矿和纤锌矿的形式存在。这两种结构都为宽禁带半导体材料，在光电子器件中有广泛应用。闪锌矿结构为立方晶系，在300K时的禁带宽度为3.54eV；纤锌矿结构为六方晶系，禁带宽度为3.91eV。纯的闪锌矿型会在1020°C时转变为纤锌矿型，但杂质的存在会使温度降低。

硫原子在闪锌矿中为立方紧密堆积，在纤锌矿中为六方紧密堆积；两种情况下，锌原子都占一半的四面体空隙。

硫化锌可通过向含Zn的溶液中通入硫化氢，并控制pH为3得到。单质化合也会产生硫化锌。

Zinc sulfide (or zinc sulphide) is an inorganic compound with the chemical formula of ZnS. This is the main form of zinc found in nature, where it mainly occurs as the mineral sphalerite. Although this mineral is usually black because of various impurities, the pure material is white, and it is widely used as a pigment. In its dense synthetic form, zinc sulfide can be transparent, and it is used as a window for visible optics and infrared optics.
