From: Vertical full-colour micro-LEDs via 2D materials-based layer transfer
a-e, Optical transmission spectra obtained from absorber layers with varying concentrations of dyes dissolved in the PI precursor (a), film curing temperatures (b), types of dye product (c), film thickness (represented as spin-coating rate) (d), and types of PI (colorless PI from Kolon, Inc. and PI-2545 from HD Microsystems, Inc.) (e). Parameters in parentheses represent conditions that apply for all data in each plot. (a, Insets) Photographs of representative absorber layers coated on glass slide.
