Project Description

Room temperature phosphorescence (RTP) from organic materials has attracted significant attention due to their potential applications as displays, chemical sensors, bioimaging, at a lower energy consumption cost and more sustainable end of life recycling. These applications benefit from long-lived excited states. Strategies for enhancing phosphoresce emission in metal-free materials include the addition of heavy atoms, heteroatoms, and crystal engineering. Recent investigations have shown that doping with organic molecules at low concentrations can significantly increase the excited-state lifetime. However, the mechanism behind this behaviour is yet to be understood. 

In this project, aided by atomistic simulations, excited state modelling and time-resolved spectroscopy, the PhD student will investigate how doping with organic molecules affect the excited-state lifetimes of RTP materials. In this project, aided by atomistic simulations, excited state modelling and time-resolved spectroscopy, the PhD student will investigate how doping with organic molecules affect the excited-state lifetimes of RTP materials and propose new combinations of host/dopant materials.

Requirements

Applications are invited from outstanding Mexican candidates with or expecting to receive a first or upper-second class master's degree in Chemistry or an area relevant to the project. A standalone master's degree, or undergraduate integrated master's degree are required for this position.

Applicants are encouraged to contact Dr Rachel Crespo-Otero on r.crespo-otero@qmul.ac.uk prior to their submission by sending a CV and a description of their interests and expertise relevant to the project.
