Triboluminescence (TL) is the emission of light induced by the application of mechanical energy to a solid. It links the spectroscopic, structural, mechanical, and electrical properties of solids. Here, materials of ZnS doped with various contents of Mn2+ were investigated. It was shown that they all have favorable triboluminescent property. The effects of the content of Mn2+, the sintering temperature and time on the luminescent property of ZnS:Mn were discussed. It was found the ZnS doped with 1.2% Mn2+ exhibited the strongest TL intensity among the materials investigated. The growth conditions were obtained through experiments, and ZnS:Mn with highly efficient triboluminescence was prepared. The mechanism of triboluminescence is proposed as follows: the electrons are excited from ground state to excited state by mechanic energy, then recombines with holes and give lights. The broad range of exciting energy may contribute to the high triboluminescent efficiency.
摩擦发光（TL）是通过对固体施加机械能而产生的光发射。它将固体的光谱、结构、机械和电学性质联系起来。在此，研究了掺杂不同含量Mn2+的ZnS材料。结果表明，它们都具有良好的摩擦发光性能。讨论了Mn2+含量、烧结温度和时间对ZnS:Mn发光性能的影响。发现在所研究的材料中，掺杂1.2%Mn2+的ZnS表现出最强的TL强度。通过实验获得了生长条件，并制备了具有高效摩擦发光的ZnS:Mn。摩擦发光的机理如下：电子通过机械能从基态激发到激发态，然后与空穴复合并发光。广泛的激发能量可能有助于提高摩擦发光效率。
