研究领域简介

本项目组主要从事半导体量子点的制备（例如： CdSe, CdS, CdSe_1-yS_y, Cd_1-xZn_xS, CdSe/ZnS, CdSe/CdS, CdSe/CdS/ZnS, ZnCdS/ZnS, 和 Zn_1-xCd_xSe/ZnSe/ZnSe_xS_1-x/ZnS等.)及其在发光显示器件中应用方面研究。

The research group is interested in synthesis of II-VI inorganic semiconductors quantum-dots (such as CdSe, CdS, CdSe_1-yS_y, Cd_1-xZn_xS, CdSe/ZnS, CdSe/CdS, CdSe/CdS/ZnS, ZnCdS/ZnS, and Zn_1-xCd_xSe/ZnSe/ZnSe_xS_1-x/ZnS etc.) and their use in quantum-dot-based light-emitting diodes

半导体量子点在显示应用中的优势：

量子点最重要的一个特性之一就是他们的带隙可调，因此可以通过控制调控带隙调控其发射和吸收(从紫外到近红外)。因为量子点具有窄的发射峰宽度 (半峰宽~30nm)，高的显色指数，宽的色域使其成为未来光电领域的优秀材料。

Advantages of Semiconductors Quantum Dot for Application to Display

One of the most important properties of Quantum Dots is the ability to tune their bandgap and therefore control their light absorbance and emission (from UV to IR region). Since quantum dots have narrow emission bandwidth (FWHM~30 nm), high colour-rendering index and broad colour gamut can be demonstrated. These great advantages make QDs excellent candidates for future optoelectronics.

量子点发光二极管

Quantum-Dot Light-Emitting Diodes (QD-LEDs)

我们采用厚壳层的核壳结构量子点构筑了高效长寿命的全彩发光二极管器件。这一结果在QD-LEDs领域是一个明显的进步为实现基于量子点的全彩显示、照明提供了一个可行的平台。

We demonstrate full-color quantum-dot-based light-emitting diodes (QD-LEDs) with high efficiency and long lifetime by employing high quantum-yield core/shell QDs with thick shells. These results are signify a remarkable progress in QD-LEDs and offer a practicable platform for the realization of QD-based full-color displays and lightings.

截止目前，本课题组已承担了量子点发光二极管相关项目5项，其中，包括，国家自然科学基金、河南省高校科技创新人才项目等。在国内外发表学术论文30余篇。

Up to date, there are 5 research projects which based on QD-LEDs are undertaken in our research group, including those from the National Natural Science Foundation of China (NSFC), Program for Science & Technology Innovation Talents in University of Henan Province. There are more than 60 academic papers from the group published in the international and domestic core journals.
