Extremely Bright Quantum Emitter Self-Heals

A new approach to synthesizing quantum dots has significantly increased their use value, according to members of an international research collaboration. The method, called spray-synthesis, was developed jointly by professor Hao-Wu Lin and associate professor Chih-Sung Chuu of National Tsing Hua University (Taiwan) and professor Richard Schaller of Northwestern University. Perovskite quantum dots have been pursued for their potential as quantum emitters, though instability has hindered their development. Unlike other quantum emitters, perovskite quantum dots are able to realize single-photon emission at room temperature and possess advantageous properties such as high quantum yield and high color purity, Lin said. However, with...
