一般描述

碘化锡(II)是一种橙色结晶固体，熔点高。广泛用于制造有机–无机太阳能电池、发光器件、二次电池等。起还原剂的作用。

应用

碘化锡(II)可用于：
  • 作为溶剂介导结晶法制备异质结耗尽钙钛矿太阳能电池所用甲基铵碘化锡薄膜的前驱体。[1][1]
  • 制备用于无铅发光二极管（PeLED）的高稳定性钙钛矿薄膜。 [2] 以及一种新型空气稳定性一维（1D）无铅杂化卤化物材料(DAO)Sn2I6，该材料在634 nm处发出宽谱橙色光，光致发光量子产率为36%。[3]
  • 作为高倍率锂空气电池的双功能电解质添加剂。SnI2通过促进Li2O2的分解来保护锂负极并降低电荷电势。[4]
  • 与甲脒亚磺酸（FSA）一起合成混合Pb–Sn钙钛矿薄膜，用于全串联钙钛矿太阳能电池。[5]

Questions

  1. This is important to whether I buy your product.I would like to ask whether 409308 and 466352 are products obtained by two different synthetic routes or 466352 was obtained by further purifying 409308. And how do you synthesize and purify Tin(II) iodide?

    1 answer

    1. The method of preparation for these products is considered proprietary; however, both items are manufactured from the same synthesized precursor. Each item is prepared using a unique method to meet specifications, i.e., powder or beaded form, purity. Neither are additionally purified.
