Blue Photoluminescence of Sol-Gel Derived SnO2:Sb Films
By varying the antimony dopant level in the sol-gel solutions, we prepared a series of antimony-doped SnO2 films on slide glass with the sol-gel technique. The transmission, absorption, photoexcitation and photoemission spectra were measured for the sol-gel derived antimony-doped SnO2 films. Under the 300 nm excitation, near untraviolet emission at 390nm and blue emission at 460 nm were recorded from thermally annealed antimony-doped SnO2 films. The effect of the ionic dopant on the photoluminescent properties of the antimony-doped SnO2 films are discussed.
