Application

InP/ZnS core shell nanocrystals are Cadmium free/heavy metal free quantum dots suitable for different applications like light emitting diodes (LEDs; display; biomedical applications. The toxicity of Cd compounds
and the corresponding regulations worldwide makes these InP/ZnS quantum dots as more desirable alternatives for consumer applications.

Since the first report of the low-cost dye-sensitized solar cell (DSSC) in 1991 by Gratzel and his coworker,1 dye-sensitized solar cells (DSSC) has been regarded as one of the most promising photovoltaic technologies because of their transparent and colorful characteristics, as well as low cost.

Professor Sharma and colleagues review the synthesis and applications of this novel material. This includes a discussion of the unique properties of quantum dots and their suitability for solar cell applications, along with common synthesis techniques used to develop these materials.

Professor Xiaohu Gao (University of Washington, USA) provides a overview of recent quantum dot (QD) advancements and their potential for advancing bioassay and bioimaging technologies.

Studies on perovskite quantum dots are developing and progress has been made toward overcoming the challenges of QDs. Strategies to fabricate high-quality materials have enabled rapid light-emitting device development.
