Electroluminescence of Insulated Particles
Keiji Maeda · Journal of the Physical Society of Japan · 1958
The origin of the local high electric field in the electroluminescence of insulated phosphor particles is considered and attributed to the disturbance of the applied field due to the conductive substance in the insulative phosphor. The distributions of local field are calculated and the dependence of brightness on the applied voltage is discussed. However, the comparison with experiments is impossible because of the complicated structure of the phosphor. Finally, the luminous efficiency of electroluminescent cell is estimated and an agreement is obtained with the observed value.
