The current study focuses on how Sr doping affects ZnO's structural, optical, optoelectronic, transport, and dielectric properties. Sr-doped ZnO nanoparticles were produced using a simple sol-gel process with a hydrothermal step procedure. Regarding Zn content, the Sr-doping levels were 0, 0.025, 0.050, and 0.075. Based on XRD, SEM imaging, XPS, UV–visible diffuse reflectance (UV–Vis DRS) spectroscopy, FTIR-ATR, and photoluminescence (PL) spectroscopies, the physico-chemical properties were deduced. A study was done on the relationship between Sr-doping degree, optical, electrical, and thermal conductivities, as well as the dielectric characteristics. Surface and bulk contributions to dissipation loss were assessed. In consideration of photon energy contributions and material formulation, the dynamics of transport were studied. The contradictory effects of Sr are discussed according to the literature, and Sr impacts were situated to Ag and B atoms.
