AB  - SnSO<sub>3</sub>/ZnSO<sub>3</sub> nanocomposite has been synthesized using the hydrothermal process. The 
complete formation of the SnSO<sub>3</sub>/ZnSO<sub>3</sub> nanocomposite is confirmed by XRD and EDAX. 
It displays a fascinating rectangular bar shape. The measured particle size is 100.4 nm. It 
will be a promising option for optoelectronic devices. Energy gap of the SnSO<sub>3</sub>/ZnSO<sub>3</sub> nanocomposite is 5.85 eV. The refractive index of the nanocomposite through its energy 
gap is found to be 1.883. The ultraviolet (~387.2 nm) area of the PL emission spectrum 
exhibits the strong efficient emission, while the green (~522.1 nm) region and the red 
(~789.4 nm) region show weak and moderate emission, respectively. Radiative electronhole
 recombination is seen in the UV emission at 387.2 nm, which qualifies the contender 
for displays/projection-based applications. Emission peaks observed in the visible region is 
attributed to various defects Frenkel or Schottky defects, Tin or Zinc interstitials and oxygen 
vacancies. The finger print region's S-O, Zn-O, and Sn-O bands are confirmed by the 
accurately assigned FTIR bands. At 300K, the sample displays diamagnetic behaviour. 
Additionally, at 5K, it displays an intriguing super paramagnetic behaviour between -0.15 
Tesla and 0.15 Tesla.
