Thermal Emission Parameters of Equimolar Compounds of Alkaline Earth Oxides and Rare-Earth Metals
Journal Title: International Journal of Advanced Biotechnology and Research. - Year 2016, Vol 7, Issue 2
Abstract
ABSTRACT The article is devoted to the study of thermal emission parameters in the oxide compounds of equimolar composition developed on the basis of alkaline earth oxides and rare earth metals RLn2O4 (where R - Sr or Ca, Ln - Y, Yb, Sc). The results of compound basic parameters calculation analysis are presented, which allow to determine the values of crystal energy values, revealing the patterns of their electrical and physical property changes in a wide temperature range which are of interest at the practical study of the considered oxides. The possibility of basic provisions application concerning the statistics of electrons in semiconductors is substantiated theoretically and confirmed experimentally for the calculation of energy performance in the oxide compounds of complex composition. The possibility of simplified relation use for the calculation of the electron output work is shown with the use of its temperature coefficient. The calculated and experimental values of the temperature coefficient concerning the operation of electron output depending on the concentration of the emission centers in oxides at a wide temperature range.
