    • Abstract

       

      Electroluminescence has been excited in the phosphor anthracene doped by 9-vinylanthracene (10−4 mole %) at room temperature (300°K). Variation of light output with voltage is governed by the relationB=B0 exp [−(C/V1/2)] as in the case of inorganic phosphors. HereB0 andC are constants andV is the rms value of the voltage applied to the phosphor. Frequency dependence of the electroluminescence has also been studied at different voltages of the applied electric field.
