Summary

Description
English: Direct visual observation of the spectral color switching of QD705s with an image spectrometer. Time-lapse image sequences of spectral blue shifting of QD705s were observed with 200 msec integration at 1 Hz for 1200 images. The spectral blue-shifting is greater in the absence of BME (left) than in the presence of 25 µM BME (right). This is evident by the greater observed migration in the position of the fluorescence emission in the direction of the spectrometer response along the y-axis. (Left) In the absence of BME, the fluorescence emission is observed to migrate upwards as a function of time corresponding to a spectral blue-shifting of the emission. (Right) In the presence of 25 µM BME, the fluorescence emission is observed to migrate slightly upwards while the peak intensity is also observed to increase as a function of time corresponding to both a slight spectral blue-shifting and photoenhancement of the emission.
