摘要:
以乙酸银、乙酸铟、硫粉和乙酸锌等为原料,按照新的化学计量比,采用热注入法制备得到一系列掺杂量为0.05~0.30的锌掺杂Ag-In-S量子点发光材料,并分析了量子点样品的微观形态、晶体结构、发光性能和量子产率。实验结果表明制得的量子点发光材料形貌为类球形,平均粒径为(5.0±0.5) nm。荧光光谱结果显示该量子点在近红外区存在广泛吸收,并且在可见光到近红外光区域均具有高发光强度。Zn2+的掺杂使得该量子点的荧光量子产率从8.34%提高到32.90%,同时功率转换效率也得到了显著提高,预计该量子点在敏化太阳能电池领域具有良好的应用前景。

Abstract:
A series of zinc-doped Ag-In-S quantum dot luminescent materials with doping amount of 0.05-0.30 were prepared by hot injection method using silver acetate,indium acetate,sulfur powder and zinc acetate as raw materials according to a certain stoichiometric ratio. The microstructure,crystal structure,luminescence properties and quantum yield of quantum dot samples were analyzed,respectively. The experimental results show that the morphology of the quantum dot luminescent material is spherical,and the average particle size is about (5.0±0.5) nm. Fluorescence spectroscopy results show that the quantum dot has extensive absorption in the near infrared region,and has high luminous intensity in the visible light to near infrared region. The doping of Zn2+ increases the fluorescence quantum yield of the quantum dots from 8.34% to 32.90%,and the power conversion efficiency is also significantly improved. The quantum dots are expected to have good application prospects in the field of sensitized solar cells.
