| Keywords: Don't Blink! NIST Studies Why Quantum Dots Suffer from 'Fluorescence Intermittency' (14444840355).jpg Experimental apparatus used to investigate quantum dot blinking A quantum dot is optically excited using a laser and its fluorescence is collected and split into two paths each equipped with a single photon avalanche diode SPAD A time correlator is used to record the arrival times of the photons on each SPAD from which the photon autocorrelation function is determined SEM images of the quantum dot devices studied include a circular grating 'bullseye' optical cavity b and a microdisk optical cavity c See also http //www nist gov/cnst/dots-052014 cfm www nist gov/cnst/dots-052014 cfm Credit NIST Disclaimer Any mention of commercial products within NIST web pages is for information only; it does not imply recommendation or endorsement by NIST Use of NIST Information These World Wide Web pages are provided as a public service by the National Institute of Standards and Technology NIST With the exception of material marked as copyrighted information presented on these pages is considered public information and may be distributed or copied Use of appropriate byline/photo/image credits is requested https //www flickr com/photos/usnistgov/14444840355/ Don't Blink NIST Studies Why Quantum Dots Suffer from 'Fluorescence Intermittency' 2014-05-06 13 52 https //www flickr com/people/63059536 N06 National Institute of Standards and Technology PD-USGov National Institute of Standards and Technology https //flickr com/photos/63059536 N06/14444840355 2016-09-07 01 31 35 United States Government Work Uncategorized 2016 December 21 | ||||
