Highly Flexible Infrared Emitter with Spatially Controlled Emissivity for Optical Security (Adv. Mater. Technol. 4/2023)
Source abstract
Abstract
Infrared Emitters In article number 2200808, Myeongkyu Lee and co-workers present a Ge2Sb2Te5 (GST)- based infrared emitter that is fabricated on a flexible substrate such as plastic and paper, and its emissivity is space-selectively controlled using a spatially modulated pulsed laser beam. The multispectral properties of GST enable different visible and thermal images to be simultaneously printed in the same area of the emitter. This provides a promising feature for optical security, including anti-forgery.
