Synthesis, Characterization and Thermal analysis of Europium and Terbiumdoped Lanthanum based compounds
Main Article Content
Abstract
Three host matrices namely of Lanthanum namely Lanthanum Oxide (La2O3),Lanthanum Oxysulphide (La2O2S) and Lanthanum Phosphate (LaPO4) were taken for this study.Each of these host matrices were activated by Europium (Eu) and Terbium (Tb) in differentconcentrations, thus generating six set of samples. The samples were characterized by X raydiffraction. The d values were found to be matching with the respective JCPDS values. Dopingbeing in minuscule proportions did not alter the peak positions.Thermal analyses confirm the highthermal stability of all doped compounds. The observed weight gain at higher temperatures iscredibly attributed to the incorporation of nitrogen species into lattice voids during high-temperature exposure in the inert environment, whichis likely toenhance the thermal robustness
and structural integrity of the materials.
