Wavelength Fluorescence (IMAGE) ARC Centre of Excellence in Exciton Science Caption Spatially-resolved steady state widefield microscopic PL image response to a carrier density gradient. The fluorescent images were simultaneously recorded at two separate wavelength regions. The image on the left presents the fluorescence at 540-570nm and the right one shows the fluorescence at 660-690nm, which perfectly respond to the remixing phase emission at the centre while the segregated phase forming a ring-like emission Credit ARC Centre of Excellence in Exciton Science Usage Restrictions Credit: ARC Centre of Excellence in Exciton Science License Licensed content Disclaimer: AAAS and EurekAlert! are not responsible for the accuracy of news releases posted to EurekAlert! by contributing institutions or for the use of any information through the EurekAlert system.
