Highly Efficient Heavy Atom Free Room Temperature Phosphorescence by Host-Guest Doping

Recently, there has been remarkable progress of the host-guest doped pure organic room-temperature phosphorescence (RTP) materials. However, it remains a great challenge to develop highly efficient host-guest doping systems. In this study, we have successfully developed a heavy atom free pure organi...
