Although the illuminating efficiency of colloidal quantum dots is close to 100%, the patterning of these nanocrystals is still important and need to be developed. We use semiconductor grade fabrication to obtain small pixels smaller than 10 micrometers and a large scale formation of array. The photonic characterization reveals the conversion efficiency is 20% and the excitation wavelength dependent behavior is also probed. A 1300-hour of vacuum storage test showed this type of color conversion layer is stable and the emission wavelength and linewidth are almost unchanged.Colloidal quantum dots | color conversion efficiency | color conversion layers | micro displays | micro LEDs | quantum efficiencyconference paper10.1002/sdtp.167602-s2.0-85175297683https://api.elsevier.com/content/abstract/scopus_id/85175297683
