报告摘要：Doping is the key to the new design of materials towards achieving enhanced performance and untapped properties. The restraint of ‘concentration quenching’, where having too many emitters too close to each other leads to a quenching of the overall luminescence, has been long challenging the field of optical luminescent materials. In my talk, I will illustrate the mechanism, and showcase new strategies that bypass the concentration quenching effect in highly doped luminescent nanoparticles, which now starts to advance the field of luminescence nanomaterials. A broad range of new design strategies and controlled synthesis to enable high doping concentrations will be discussed. Our particular emphasis will be on the new optical properties and their superior performance in a wide range of emerging applications, including single molecule sensing, colour tuning, optical multiplexing, lasing, and super resolution nanoscopy。
