Band gap narrowing and fluorescence properties of nickel doped SnO{sub 2} nanoparticles

Abstract

Nickel-doped tin oxide nanoparticles (sub-5 nm size) with intense fluorescence emission behavior have been synthesized by sol-gel route. The structural and compositional analysis has been carried out by using XRD, TEM, FESEM and EDAX. The optical absorbance spectra indicate a band gap narrowing effect and it was found to increase with the increase in nickel concentration. The band gap narrowing at low dopant concentration (<5%) can be assigned to SnO{sub 2}-SnO{sub 2-x} alloying effect and for higher doping it may be due to the formation of defect sub-bands below the conduction band.
