In essence, the emitted light changes its color, intensity, and randomness according to the material\u2019s properties and its temperature. The <a href=\"https:\/\/opg.optica.org\/abstract.cfm?URI=optica-13-5-829\" target=\"_blank\">discovery<\/a> was published in <i>Optica<\/i> and opens new possibilities for designing advanced light sources, optical sensors, and thermally based photonic systems.<\/p>\n<p>The research was led by M.Sc. student Tomer Bar-Lev and Prof. Carmel Rotschild from the Faculty of Mechanical Engineering and the Russell Berrie Nanotechnology Institute at the Technion. According to the researchers, the central phenomenon examined in this work is photoluminescence, a process in which a material emits light in response to incident illumination. In this phenomenon, light particles (photons) are absorbed by the material and re-emitted, forming the basis of many technologies, including LED lighting and optical sensors.<\/p>\n<p>The Technion researchers demonstrated that the influence of fundamental physical laws formulated more than a century ago is far broader than previously thought.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Technion researchers have developed, for the first time, a comprehensive physical model explaining how the properties of a radiating material, including absorption, emission, and quantum efficiency, affect the fundamental characteristics of the light it emits as a function of temperature.
