Abstract

The main aim of my research is to improve the NLO properties of KDP crystal by doping with organic impurities. KH2PO4 (KDP) crystal is widely used and thoroughly studied NLO crystals. The NLO and other properties of the crystal have been improved by doping of organic impurities. In the present investigation, Pure and dyes (Sudan I, Methyl Red and Evans blue) doped KDP crystals were grown by slow evaporation technique at room temperature. Grown crystals have been characterized using single crystal X-ray diffraction, Fourier Transform Infrared Spectroscopy (FTIR), UV- visible spectroscopy and NLO studies. The presences of dyes were confirmed by FTIR and XRD spectra. Dye molecules possess π electron similar to conjugated polymers, but the molecules themselves are not very big. The analysis of single crystal XRD spectra conforms that all the doped samples have the perfect crystal properties. Their energy level structure shows the presence of bands containing many closely spaced levels corresponding to vibrational and rotational states. A variety of dyes for many laser operating wavelengths were employed in the past. The NLO reports of the samples are having high energy level comparing with pure KDP. Dyes embedded in KDP crystal and dye doped crystal were also reported as useful non-linear optical media.
