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 …
