Toward Smart Light Sources
Researchers at the Technion have developed the first comprehensive physical model linking the properties of luminescent materials to the fundamental characteristics of the light they emit. The model shows how factors such as absorption, emission, quantum efficiency, and temperature determine the color, intensity, and statistical nature of emitted light.
Led by M.Sc. student Tomer Bar-Lev and Prof. Carmel Rotschild, the study expands classical theories by Planck and Kirchhoff beyond thermal equilibrium, providing a general framework that applies to all types of radiation. The model reveals how increasing temperature gradually shifts light emission from narrow, LED-like spectra to broad, sunlight-like radiation.
Published in Optica, the findings enable prediction and design of light emission properties, opening new possibilities for advanced light sources, optical sensing, communication technologies, and thermal photonic systems.
