High Performance, Full-Color Light-Emitting Devices Based on Perovskite Colloidal Quantum Dots

Reference number
Coordinator Linköpings universitet - IFM, Linköping University
Funding from Vinnova SEK 2 141 981
Project duration July 2016 - August 2019
Status Completed

Purpose and goal

The overall purpose of this project is to build collaborations between Linköping University and University of Cambridge (UK) as well as Nanyang Technological University (Singapore) through joint research activities on developing high performance and full-colour light-emitting devices (LEDs) using perovskite quantum dots. During the grant period, we have realized blue, green, red, and near-infrared perovskite LEDs with EQEs up to 5%, 7%, 11%, and 16%, respectively, and have established long-term collaborations with the two partners.

Expected results and effects

The outcomes of this project include 8 published scientific papers, three of which are jointly published with the partners. Aside from the research results, this fellowship also leads to lasting collaborations between the host organization and the partners in both research and joint funding applications. In addition, the fellow has been well trained through this fellowship in the aspects of multidisciplinary knowledge, research supervision, communication, networking and attracting research funds, which have helped him to secure an assistant professor position.

Planned approach and implementation

We have realized blue, green, red, and near-infrared perovskite LEDs with EQEs up to 5%, 7%, 11%, and 16%, respectively, by optimizing perovskite materials and device structures. In addition, we have successfully in situ prepared perovskite quantum dots, of which the properties are comparable to colloidal perovskite quantum dots yet without sophisticated chemical synthesis processes. We have also established close and long-term collaborations with the partners through transnational research activities and joint funding applications.
