Visualizing near-infrared light (6 units) - Student id: 18208762
With rapid technological development and economic growth, the development of technologies related to environmental pollution detection, health and security monitoring have attracted increasing interest. We are currently facing a series of environmental challenges including ocean pollution, soil quality deterioration, fog and haze, and so on. To prevent further harm to the environment, as well as to people, normative rules and systematic monitoring techniques should be established. In this project, a high performing solution-processable near infrared (NIR) to visible light up-conversion device, comprising an NIR detector and a light-emitting unit, will be investigated for visualizing the NIR light.
This FYP project comprises two components:
1) To study the properties of organic photodetectors for NIR detection
2) To measure and analyze the NIR visualizing devices for application in health monitoring.
Research students will also work closely with Crimson Vision Technology Limited, a Hong Kong based Start-up Company, to develop NIR detecting technologies.
Perovskite light-emitting diodes (6 units)
The performance of perovskite light-emitting diodes (PeLEDs) has been substantially improved over the past few years. However, the related fundamental physics is still far from adequate. This project will study the factors for controlled growth of cesium lead tribromide (CsPbBr3) perovskite crystals. The primary focus of the research is to understand the electroluminescence properties of solution-processable CsPbBr3-based PeLEDs through improved understanding of charge injection, suppression of trap density in CsPbBr3 emitting layer, and the stability of the PeLEDs,
The research work will comprise three key components: (1) to understand the electroluminescence processes in PeLEDs, (2) to study the effect of additives in the CsPbBr3 precursor solutions on the growth of CsPbBr3 crystals, and (3) to analyze charge transport property in PeLEDs.
