Abstract : Zn2SnO4 microcubes with interlocked morphology were synthesized using simple chemical precipitation technique using Zn(CH3COO)2·2H2O and SnCl4·5H2O as the reagents. The structural characterization using X-ray diffraction confirmed the formation of inverse spinel structure. The bandgap shift owing to Burstein–Moss shift and effect of Zn/Sn stoichiometry on luminescence property of the synthesized sample is discussed in detail. The additional SnO2 peaks obtained from Raman spectrum also confirm the influence of Zn/Sn stoichiometry. The mixed cubic-nanoplate morphology of nanoparticles was confirmed from FESEM analysis. The dielectric-dc conductivity studies of the sample confirmed the semiconducting nature and n-Zn2SnO4/p-Si junction diodes were fabricated which exhibited good photoresponse.
