QDs were patterned by ink-jet printing and by photolithography to from QD array with pitch/size of 40/20 Pm respectively, and were further excited by a blue LED for luminescent property measurement. QD ink-jet printing pattern shows red light emission peak of 626 nm and a FWHM of 38 nm. Compare to ink-jet printing method, QD photolithography pattern shows the emission peak with longer wavelength of 635 nm and a broadened FWHM of 43 nm.colloidal quantum dots | ink-jet printing | micro LEDs | quantum dot photoresistconference paper2-s2.0-85175263402https://api.elsevier.com/content/abstract/scopus_id/85175263402
