hollow nanosphere (HNS) was synthesized by a carbon sphere (CS) template-assisted in solution phase growth method using Tin (IV) chloride (SnCl

). This HNS is fabricated or formed by aggregations among the adjacent SnO

nanoparticles at above 100 °C temperature. The difference between the valance and conduction bands gap is found to be 3.387 eV. The whole diameter of the SnO

HNS is ranged from 300–500 nm in size with the thickness of the wall 40–50 nm. The SnO

nanoparticle size ranges from 20 to 30 nm. The dimension of the HNS are controlled by adjusting the some parameters, such as the concentration of SnCl

, the aging time, temperature, and the size of carbon spheres. The whole HNS size and wall thickness are affected by the Sn
4+
, due to the electrostatic force between CS and metal ions. The fabricated semiconductor SnO

HNS was characterized by various analytical methods such as diffusion reflectance spectrum, Fourier transform infrared spectra, an X-ray diffraction pattern, Energy-dispersive X-ray pattern, Field emission scanning electron microscope (FESEM), and High-resolution transmittance electron microscope. Then, this semiconductor SnO
