Doping metals with titanium dioxide (TiO2) has gained significant attention due to its ability to enhance the properties and performance of various metal- based materials in several fields such as catalysis, energy storage and environmental applications. In this study, pure TiO2 as well various concentrations of copper (Cu) and silver (Ag) doped TiO2 nanoparticles were synthesized by solvothermal method using Titanium (IV) tetra-isopropoxide as precursors. The TiO2 samples were prepared as follow: pure TiO2, TiO2 doped with 1.5% Cu:1% Ag, 1% Cu:1.5% Ag and 1% Cu:1% Ag nanoparticles named as, T0, T1, T2 and T3, respectively. The samples were annealed at 500 °C for 2 hours and characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR), field emission scanning electron microscopy (FESEM), energy dispersive Xray-spectroscopy (EDX) and photoluminescence spectroscopy (PL). The results of XRD indicated that doping TiO2 with Cu and Ag ions leads to a reduction in average crystallite size compered to pure TiO2, the average crystallite size of T0, T1, T2 and T3 were found to be 13.56, 12.73, 13.03 and 12.67 nm, respectively. FESEM imaging revealed spherical nanoparticles with little agglomeration, while EDX analysis confirmed the successful incorporation of Cu and Ag into the TiO2 matrix, with distinct peaks corresponding to Ti, O, Cu and Ag. The results of PL show that the Cu/Ag-doped TiO2 nanoparticles decrease the recombination rate of photo-induced electron−hole pairs.
