纳米晶体具有跨越生物医学成像、发光器件和电子消费产品的多种应用,其独特的光学性质是由其组成的晶体类型产生。然而,迄今为止纳米晶体发展的主要瓶颈是需要X射线技术来确定晶体类型。伊利诺伊大学香槟分校的研究人员已经开发了一种新颖的基于光学的方式来确定晶体类型,即通过晶体吸收光的独特方式来鉴别。研究人员开发的这种新方式消除了对慢速和昂贵的X射线设备的需要以及大量必须高纯化的材料需 Nanocrystals have applications spanning a wide range of biomedical imaging, light-emitting devices and consumer electronics products, whose unique optical properties result from the crystal types that make up them. However, the main bottleneck in the development of nanocrystals so far has been the need for X-ray techniques to determine the crystal type. Researchers at the University of Illinois at Urbana-Champaign have developed a novel optical-based approach to determining crystal type, which is uniquely identified by the crystal’s ability to absorb light. The new approach developed by researchers eliminates the need for slow and expensive X-ray equipment and the large amount of material that must be highly purified
