Nd3+ doped TiO2 and undoped TiO2 were produced by the complication free hydro thermal synthesis process. The doping has reduced the bandgap of the tailored material compared to its purest form. The UV–vis spectroscopy and Photo Fluorescence spectroscopy are employed to study the characteristics of the synthesized material and the results drawn from the characterization vouch that the gap between the CB and VB has minimized. The absorption peak calculated using the spectro-flourometer asserts that Nd3+ doped TiO2 can be utilized well in the UV-A and UV-B regions along with the visible region of the solar light. This expansion in the area will enhance the efficiency of the solar cells.
