摘要/Abstract

摘要： 采用化学输运法制备了一系列CdxZn1-xSe合金量子点。通过对量子点的调控，改变量子点中Cd与Zn的组分，可有效地调控合金量子点的吸收带边，同时可以在524―627nm之间实现对CdxZn1-xSe合金量子点发射峰位的连续调控。并且利用量子点的可调色性，讨论了基于基于CdxZn1-xSe量子点多路发光的安全识别设计原理，认为这种新型的隐形防伪技术将有望应用于超市标签，安全系统和护照等领域。

Abstract: The single crystals of CdxZn1-xSe were prepared by chemical transport method. We change the luminescence center of the information carrier through adjusting the composition of the alloy quantum dots. The alloyed nanocrystlas show composition-tunable optical band gap energy and their emission can be tuned continuously in the range of 524 to 627 nm．Here,we discussed the multicolor optical coding for engineering assays through coating different-colored quantum dots onto the anti-fake label,which further resulting in a new security identification system. The multiple luminescent CdxZn1-xSe quantum dots based anti-fake system can be applied to supermarket labeling,military security and object identification.
