Other information:

The current research activities include the synthesis and characterization of Display Device Materials, Ferrites, Ferroelectric Ceramics, Sensor materials, Sol-Gel Synthesis, Ion Beam Modification of Materials and Nanosystems. Different preparative methods are employed for the synthesis of bulk as well as nanosystems. Experimental tools such as X-ray diffractometry, Spectrofluorophotometry, UV-Vis_NIR spectrometry, FTIR spectroscopy, PA spectroscopy and Neutron Scattering techniques are employed for the characterization of structural, optical and thermal properties of the samples synthesized. Some of the activities are being carried out in collaboration with Bhabha Atomic Research Centre (BARC), Mumbai, Nuclear Science Centre (NSC), New Delhi and Cochin University of Science & Technology, Kochi, Kerala. The research group include Ph. D and M. Phil students.
