Abstract
- Gadolinium and Thulium doped SrTiO3-δ i.e. Sr1-xGdxTi1-yTmyO3-δ for various values of 'x' and 'y' have been successfully synthesized using sol gel technique in the reported work. XRD patterns of the obtained ceramics are found to be sharp and well defined having no impurity phases for all the compositions. The lattice parameter 'a' decreases with increase in amount of Gadolinium. XRD, FESEM and EDX studies confirm the formation of Sr1-xGdxTi1-yTmyO3-δ ceramics with required cubic structure. FESEM/EDX analysis reveals that ceramics possess high density with marginal inter-granular porosity. The dielectric studies show that the synthesized samples possess high dielectric constants, high ac conductivity and low loss factors; and furthermore, dielectric properties improve on doping with gadolinium and thulium.
