... excellent absorbance in UV range (200–300 nm) and also that with an increase in the alkali-doping concentration, shifts absorbance peaks slightly toward higher wavelengths, suggesting enhancement in the particle size. In these alkali-doped samples, it was observed that ionic conductivity decreases...
