Frank Fichert,Hans-Helmut Grandjot selected semiconducting material should double or treble the light output of an incandescent lamp. It is also shown that the efficiency of injection-electroluminescence light sources may approach 100%.

https://doi.org/10.1007/978-3-531-90337-8 it possible to draw some conclusions about the mechanism which governed the electroluminescence brightness. It was concluded that the physical meaning of the parameters deduced from the temperature dependence of the brightness should be approached with great caution.

Kinetics of the Destriau Effect, used to derive an expression for the electroluminescence efficiency. The results are given of an experimental study of the dependence of the electroluminescence efficiency on the voltage applied to capacitors containing ZnS:Cu phosphors with different concentrations of copper. These experimental results are compared with the theory.

Impact of Pedagogical Agents’ Conversational Formality on Learning and Engagementhe agents’ informal discourse yielded higher performance, but elicited higher report of text difficulty and mind wandering. This discourse also caused longer response time and lower arousal. The implications are discussed.
