Abstract

Abstract: Printing technology has led to a multitude of revolutions in design, conception, fabrication, and application of optoelectronics nowadays especially for wearables and one‐off devices. Recent advances range from solar cells, batteries, sensors, LEDs, displays, biomedical widgets to smart tags. Inkjet‐printed random lasers (IPRLs), demonstrated here, fill in the crucial but missing piece of the puzzle in printed optoelectronics as well as progress in laser research. A broad emission spectrum of IPRL inks covering more than 75% gamut of CIE color space is successfully exploited and well adopted by commercial desktop inkjet printers. Furthermore, based on the digital, ink‐efficient, mask‐free patterning, and drop‐on‐demand printing technique, a series of long‐anticipated proofs‐of‐concept including on‐chip laser lighting modules, red‐yellow‐green‐blue pixel‐based laser displays, and ink‐crypto/laser‐coded security printing technique are also demonstrated. Abstract : Inkjet‐printed random lasers (IPRLs) with red‐yellow‐green‐blue (RYGB) monochromatic inks are systematically designed and imported into commercial desktop inkjet printers. Several novel proofs‐of‐concept including on‐chip white laser lighting modules, RYGB pixel‐based laser displays, and laser‐encrypted prints/codes are successfully demonstrated. It is believed that IPRLs can be further applied to a variety of areas, including intelligent‐paints, biomedical opto‐microfluidics, and photonic integrated‐circuits.
