“…Such observation in pure and doped KDP as well as in many other NLO crystals grown by slow evaporation solution technique as well as grown by SR method was also observed previously. 22,23,29,30,[57][58][59][60] . From Figure 10(b), it is clear that the dielectric loss has similar behaviour as dielectric constant and depends on frequency.…”

“…Various reports are available on the bulk crystal growth of pure and doped KDP as well as many other materials by Sankaranarayanan-Ramasamy (SR) method and various properties such as growth rate, optical transparency, crystalline perfection, laser damage threshold, mechanical and dielectric etc., were found to be enhanced in comparison to slow evaporation solution grown crystals. [21][22][23][24][25][26][27][28][29][30][31][32][33][34][35] For the pure and L-threonine-doped KDP crystals that have been grown by slow evaporation solution technique, the growth rate and various properties such as crystalline perfection, second harmonic generation efficiency, optical transparency and laser damage threshold of KDP were found to be enhanced. 36 Because of the strong effect of L-threonine (LT) doping on physical properties KDP crystals, 36 we have decided to grow As per the current available literature, there is no report on bulk growth of LT-doped KDP crystals by SR method so far.…”

In the present work, the authors have grown the bulk-sized single crystals of pure (Size ~ 45 × 10 × 10 mm 3 ) and first time L-threonine (LT)-doped (Size ~ 85 × 10 × 8 mm 3 ) KDP with high quality by Sankaranarayana-Ramasamy (SR) method in an aqueous solution at constant temperature. A remarkable enhancement in the growth rate was observed from 3.2 mm/day (pure) to 6 mm/day (LT doped), respectively. The crystal structure, lattice parameters and growth direction were confirmed by powder X-ray diffraction analysis. FT-IR study confirms the presence of L-Threonine doping in KDP. Further, the vibrational modes and surface morphology was studied by FT-Raman spectroscopy along with etching treatment and shows remarkable reduction of surface defects. The optical transparency of SR-grown KDP crystals was found to be enhanced from 76 to 88% due to LT doping. The optical band gap was calculated for both the crystals and found to be 5.68 and 5.53 eV. Crystalline perfection of the grown crystals was assessed by high-resolution X-ray diffraction, dielectric and wet chemical etching studies and found to be good. The obtained result shows that the grown crystals can be used for laser applications.

The semi-organic non linear optical single crystal of L-proline cadmium chloride monohydrate was successfully synthesized and the single crystal was grown by a slow evaporation solution growth technique, using double distilled water as the solvent. The lattice dimensions of the grown crystal were examined by powder X-ray diffraction and it was found to belong to the orthorhombic crystal system with a noncentrosymmetric space group. Its crystallinity was assessed by a high resolution X-ray diffraction method and its structural imperfections were recorded using X-ray topography. The presence of functional groups was identified from heteronuclear correlation methods. Its optical behavior was examined by birefringence and photoluminescence and its optical constants were determined from UV-Vis. analysis. Its thermal and third order nonlinear optical properties were characterised by photopyroelectric and Z-scan methods, respectively. The mechanical and ferroelectric behavior was also assessed on the grown single crystal of L-proline cadmium chloride monohydrate.

“…Recently, nonlinear optical (NLO) materials have been found to have important applications in, for example, opto-electronic, photonic, data conversion, retrieval, storage and frequency-doubling devices (Saleh & Teich, 1991;Penn et al, 1991;Shakir et al, 2009;Shakir, Kushwaha et al, 2010;Shkir, Abbas et al, 2014;Badan et al, 1993;Zaitseva & Carman, 2001;. Luminescent dyed crystals exhibit better properties than polymers and glasses as they possess superior thermal conductivity, low dispersion and intrinsic polarization, have fewer defects, and can be used in laser devices (Yang & Ozin, 2000, Wanke et al, 1997.…”

Effect of phenol red dye on monocrystal growth, crystalline perfection, and optical and dielectric properties of zinc (tris) thiourea sulfate

In this work, the growth of large size ($25 Â 29 Â 5 mm and $25 Â 24 Â 6 mm) colorful single crystals of zinc (tris) thiourea sulfate (ZTS) in the presence of 0.05-2 wt% phenol red (PR) dye was achieved using a simple and low-cost technique. Powder X-ray diffraction patterns confirm the presence of PR dye, which is indicated by an enhancement of the Raman peak intensities, a shift in their position and the appearance of a few extra peaks. The quality of the grown crystals was assessed by high-resolution X-ray diffraction, which shows that the crystalline perfection of 1 wt% PR-dyed ZTS crystals is better than that of 2 wt% PR-dyed crystals. The measured UV-vis absorbance spectra show two additional, strong absorption bands at $430 and 558 nm in the dyed crystals, due to the presence of PR dye, along with a band at $276 nm which is present for all crystals but is slightly shifted for the dyed crystals. Photoluminescence spectra were recorded at two excitation wavelengths ( exc = 310 and 385 nm). The luminescence intensity is found to be enriched in dyed crystals, with some extra emission bands. An enhancement in the value of the dielectric constant and a.c. electrical conductivity was also observed in the dyed ZTS crystals.
