Abstract
In the present study we have investigated the extinction spectra of coated sphere using dipole model with different core–shell radius in which the core is TiO2 and the shell is made up of silver or gold nanoparticles Nanoparticles exhibit surface plasmon resonance peak these plasmonic peaks are highly tunable in wavelength range of 300 to 1100 nm in fact the blue and red shifting of resonance peak highly depends on the core–shell thickness The broadness of resonance peaks are analysed in terms of full width at half maxima FWHM and the width of these resonance peaks is also the function of core–shell radius
