ABSTRACT
Gel grown lead iodate crystals doped by 0.04 M cobalt were characterized by Raman, Fourier transform infrared (FT-IR) spectroscopy and thermo analytical techniques (thermogravimetric and differential thermal analyses). The Fourier transforms infrared and Raman spectrum reveals various vibrational modes characterizing particular functional group. The investigation confirms the existence of iodate group. Thermal analysis shows that thermal stability of lead iodate crystals decreases slightly due to cobalt doping. The effect of doping is reported and discussed in detailed.
