Title: Non-blinking semiconductor colloidal quantum dots for biology, optoelectronics and quantum optics. Author: Spinicelli P, Mahler B, Buil S, Quélin X, Dubertret B, Hermier JP. Journal: Chemphyschem; 2009 Apr 14; 10(6):879-82. PubMed ID: 19294684. Abstract: Twinkle, twinkle: The blinking of semiconductor colloidal nanocrystals is the main inconvenience of these bright nanoemitters. There are various approaches for obtaining non-blinking nanocrystals, one of which is to grow a thick coat of CdS on the CdSe core (see picture). Applications of this method in the fields of optoelectronic devices, biologic labelling and quantum information processing are discussed.The blinking of semiconductor colloidal nanocrystals is the main inconvenience of these bright nanoemitters. For some years, research on this phenomenon has demonstrated the possibility to progress beyond this problem by suppressing this fluorescence intermittency in various ways. After a brief overview on the microscopic mechanism of blinking, we review the various approaches used to obtain non-blinking nanocrystals and discuss the commitment of this crucial improvement to applications in the fields of optoelectronic devices, biologic labelling and quantum information processing.[Abstract] [Full Text] [Related] [New Search]
