Overview
Demosthenes (Demos) Koutsogeorgis is an Associate Professor of Photonic Technologies at Nottingham Trent University (NTU). He has over 20 years of experience in R&D projects, with academia and industry, on laser processing of thin‐film materials. Projects led by Demos lie in the scientific area of materials science for nanotechnology applications in plasmonics, electronics and light emitting devices. Applications span several industries including those of photovoltaics, data storage, security and authentication, medical devices, optoelectronics, thin film transistors, quantum computing, displays, smart coatings, functional materials.
Humankind has always been fascinated by light and has long relied on it also (for supporting life, for communications, for entertainment etc). But beyond that, manipulated appropriately, it becomes a tool like no other. It is fast, precise, sterile, selective and highly energetic. It delivers unique processes and materials of unparalleled qualities.
