Abstract
The statistical distribution of phosphor crystals in the solid dielectric material of a practical electroluminescent lamp influences the observed characteristics of the lamp. Calculation on the basis of a very simple model shows that maximum efficiency is favored by high phosphor concentration, fine particles, and thick phosphor layers; the slope and intercept of the usual brightness voltage plots are affected by the same variables. Measurements on electroluminescent lamps with these variations are in substantial agreement with the predictions.This publication has 11 references indexed in Scilit:
