以乙酸锌为锌源,Na2SeO3·5H2O或Se粉为硒源,采用溶剂热法在乙醇胺(EA)溶剂中—步合成晶型和形貌可控的闪锌矿和纤锌矿结构的ZnSe纳米材料.利用X射线衍射(XRD)、能量色散X射线谱(EDS)、扫描电子显微镜(SEM)和透射电子显微镜(TEM)对产物的晶型、成分和形貌进行了表征.结果表明,Se源的选取直接决定了ZnSe纳米材料的晶型和形貌:以Na2SeO3·5H2O为源,产物为立方相闪锌矿结构的ZnSe纳米颗粒,直径30 nm左右；以Se粉为源,产物为六方相纤锌矿结构的ZnSe纳米片,厚度约50 nm.进一步的研究表明,具有合适配位能力的乙醇胺溶剂和Se源对ZnSe纳米结构的合成起重要作用.通过紫外-可见光谱(UV-Vis)和室温光致发光光谱(PL)表征了产物的光学性质.
