Abstract

In present work, Cu₂BaSnS₄(CBTS) nanoparticles are reported solvothermally synthesized. The formation of single-phase trigonal structure of CBTS nanoparticles is confirmed by XRD and Raman spectroscopic analysis. SEM studies reveal that CBTS exhibits flower shaped structure self-assembling by nanosheets with uniform average thickness 30nm. CBTS materials show abroad absorption in the complete visible range, providing a band-gap value of 1.58eV, indicating potential applications in photocvoltaics. The excellent MB degradation efficiency of 93% under visible light within 100min is achieved, suggesting CBTS is a potential material for effective solar light photocatalytic application. Meanwhile, electrical properties are measured up to 675K, the value of Seebeck coefficient of CBTS material can reach to 111.42μV•K^-1 , meanwhile the value of electrical conductivity is 18.24S·m^-1 , indicating its potential for thermoelectric application.
