Jin Chang received his Ph.D. degree in nanotechnology and molecular science from Queensland University of Technology in Australia in 2013. Then, he worked as a postdoctoral researcher at the University of Electro-Communications in Japan, and investigated on PbS quantum dot heterojunction solar cells for two years. In 2015, he joined the Institute of Advanced Materials (IAM) of Nanjing Tech University as an Associate Professor. Currently, his research interests mainly include the lead-free perovskite light-emitting diodes and novel non-toxic metal halide luminescent materials for X-ray detecting.
