【Abstract】 In this paper, a new type of transparent thin films of electroluminescence and electric heating device are discussed. The characteristics of electric and optic of this device are studied on the basis of experiments. The results show that the Sb contents have great effect on the special properties of the films. When the Sb contents are little, the square resistance reduces with the Sb contents increasing, and the resistance temperature characteristics take on negative temperature characteristic. When Sb contents are above a special quantity, the square resistance increases with the Sb contents increasing, and the resistance-temperature characteristics display positive temperature characteristic. And the visible transmission of the film is higher than 80%. The electroluminescent spectra are between 500?nm～600?nm and the peak is located at the point of 585?nm. The brightness grows as the voltage increases and it will stop growing when the voltage is too high..更多还原
