Synthesis and characterization of PBS/PVA Nanocomposite film

Author:

Kannan, A. and Shanmugam, G.

Subject Area:

Physical Sciences and Engineering

Abstract:

The nanocomposite film of lead sulphide nanoparticles and poly vinyl alcohol has been prepared by chemical synthesis method. Lead nitrate and sodium sulphide were used as lead (Pb2+) and sulphur (S2-) ion sources respectively. X-ray diffraction pattern revealed the cubic structure of PbS. Formation of the nanocomposite film is confirmed using the FTIR. Photoluminescence spectrum exhibited the two emission peaks corresponding to the blue-green and green emission of PbS. Electrical properties of PbS film were measured using impedance analyzer in the frequency range of 1 kHz to 1 MHz and in the temperature range of 303-348 K.
