VSN

First-principle Calculation ( by VASP) indicates that the yellow luminescence derives from the Sn vacancy ( VSn). Solvent-thermal method is in a critical condition, can occur under the normal conditions the reaction can not be achieved, and can generate metastable state structure of materials.

第一性原理计算表明所激发的黄光发射来自于锡空位（Vsn）。溶剂热法中有机溶剂处于临界状态下，能够发生通常条件下无法实现的反应，并能生成具有介稳态结构的材料。
