| 摘 要： | 本文报道了ZnS:Mn具有良好摩擦发光性能。研究了ZnS:Mn发光中心Mn^2 及其含量以及样品的灼烧温度、灼烧时间等条件对样品发光特性的影响。优化浓度配比和制备条件制备出了较高摩抢擦发光效率的ZnS:Mn摩擦发光材料。摩擦发光机理可能是由于机械能使ZnS:Mn的电子从基态激发到激发态所致，而具有较高的摩擦发光效率可能来源于ZnS:Mn具有较宽的激发能量范围。

| Abstract: | 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 Mn 2+ were investigated. It was shown that they all have favorable triboluminescent property. The effects of the content of Mn 2+ , the sintering temperature and time on the luminescent property of ZnS:Mn were discussed. It was found the ZnS doped with 1 2% Mn 2+ 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. |
