摘要

摘要采用水热法制备了ZSSG (ZnSSe/rGO)复合材料。通过各种试验研究了其结构、形貌和材料性能。与ZnSe相比，ZnSSe的衍射峰移动了更大的角度，位于立方相ZnSe和立方相ZnS之间。含20% wt.%石墨烯的ZSSG20光电流密度为2.17×10−5 A cm−2，是纯ZnSSe光电流密度的8.9倍。ZSSG20具有最小的电荷转移电阻和最高的载流子密度。PL光谱中荧光强度的降低表明石墨烯可以有效地阻止电子空穴对的复合。

ZnSSe Decorated Reduced Graphene Oxide for Enhanced Photoelectric Properties

Abstract ZSSG (ZnSSe/rGO) composites are prepared by a hydrothermal method. The structure, morphology and material properties are investigated by various tests. Compared to ZnSe, the diffraction peaks of ZnSSe are moved to a larger angle and located between cubic phase ZnSe and cubic phase ZnS. The photocurrent density of ZSSG20 with 20 wt.% graphene is 2.17×10 −5 A cm −2 , which is 8.9 times higher than that of pure ZnSSe. ZSSG20 has the minimum charge transfer resistance and highest carrier density. The decreased fluorescence intensity in PL spectra indicates that graphene can effectively prevent the recombination of electron‐hole pairs.
