Crystalline Zn1−x Si x O(0 ≤ x ≤ 0.156) nanoparticles reveal decreasing particle size with increasing Si content and a undistorted wurtzite form until x = 0.062 beyond which local deformation is observed maintaining the parent structure. There is a sharp increment in bandgap with nominal Si-doping and then almost saturates onwards. Moreover thermal annealing demonstrate the increase bandgap and decreasing lattice parameters. The details of samples synthesis and characterization is presented in the present manuscript.
