From: Direct ambient photopatterning of RGB quantum dots for light-emitting diodes with EQE exceeding 20%
Changes in PLQYs of red- (a), green- (b), and blue- (c) emitting QDs-TPP films at various stages for patterning. d patterned lines of blue-emitting QDs and an AFM image of lines patterns (inset). Scale bars, 10 μm. e SEM images of pristine and patterned QDs films. Scale bars, 50 μm. f Height profiles and an AFM image of line patterns. g Pixelated blue-emitting QDs and an AFM image of dots patterns (inset). Scale bars, 10 μm. h Images of SEM (left), AFM (right) of multilayer line patterns created by using red- and green-emitting QDs. Scale bars, 10 μm.
