摘要/Abstract

摘要：

以醋酸锌和硫代硫酸钠为原料,十六烷基三甲基溴化铵(cetyltrimethyl ammonium bromide, CTAB)为表面活性剂,低温简单水热法合成了ZnS微球。通过XRD、TEM、SEM、FT-IR等表征手段对产品ZnS微粒进行了结构和形貌分析。结果表明:ZnS粒子为微球结构,属于立方闪锌矿结构,粒径在3μm左右,且分散性良好,球形度高;在1116cm^-1、618cm^-1、495cm^-1处出现Zn—S键的红外特征吸收峰。同时对ZnS微球的可能生长机理进行了探讨。

Abstract:

Monodispersed ZnS microspheres were hydrothermally synthesized under low temperature using zinc acetate and sodium thiosulfate as raw materials, and cetyltrimethyl ammonium bromide (CTAB) as surfactant. The particles were characterized by XRD, TEM, SEM and FT-IR. The results showed that the smooth particles were of cubic phase, well-dispersed and had uniform size of 3 μm in diameter, and the characteristic absorption peaks of Zn—S appeared in the FT-IR spectra. Also, the possible growth mechanism was discussed.

Key words: ZnS, hydrothermal synthesis, microspheres, growth mechanism
