Abstract
Non linear optics (NLO) materials have acquired a new significance with the advent of a large number of devices utilizing
solid – state lasers sources and wide applications in the field of telecommunication, optical data storage and information
devices. The Di-sodium hydrogen phosphate (DSHP) is a well known inorganic NLO material for various optoelectronics
applications. In the present investigation we have grown thiourea doped Di- sodium hydrogen phosphate crystal from the
aqous solution. We could enhance the SHG efficiency of thiourea doped DSHP crystal. It was 2.2 times more than pure
DSHP. We observed the large enhancement in nonlinearity for high concentration of thiourea. The powder X-ray diffraction
analysis confirmed the crystal structure. The incorporation of thiourea in the grown crystal was qualitatively analyzed from
FT-IR study. The UV-Visible spectral study revealed that the incorporation of thiourea in DSHP enhances the transmittance
of DSHP. The thermal study of grown crystal was carried out by thermogravimetric analysis.
