Halogen-doped phosphorescent carbon dots for grayscale patterning
文献摘要：
Flexible organic materials that exhibit dynamic ultralong room temperature phosphorescence(DURTP)via photoactivation have attracted increasing research interest for their fascinating functions of reversibly writing-reading-erasing graphic information in the form of a long afterglow.However,due to the existence of a nonnegligible activation threshold for the initial exposure dose,the display mode of these materials has thus far been limited to binary patterns.By resorting to halogen element doping of carbon dots(CDs)to enhance intersystem crossing and reduce the activation threshold,we were able to produce,for the first time,a transparent,flexible,and fully programmable DURTP composite film with a reliable grayscale display capacity.Examples of promising applications in UV photography and highly confidential steganography were constructed,partially demonstrating the broad future applications of this material as a programmable platform with a high optical information density.
