Lowest visible temperature incandescence
WebPour les ampoules à filament (incandescence et halogène), les températures sont toujours inférieures à 3695 K (fusion du tungstène). Le rendement lumineux augmente très vite avec la température du filament. WebLaser-induced incandescence (LII) of a surface layer of GaSb/In x Ga 1−x Sb/GaSb (x = 0.1) sandwich heterostructure is investigated in the visible spectral region under irradiation by the third harmonic of radiation of a Q-switched YAG:Nd 3+ laser. Within the laser-induced hot spot on the irradiated surface, strong granularity of LII is observed.
