“…The reports of plane wave dynamical theory of X‐ray diffraction suggest that the material with less full width half maxima (FWHM) exhibit good crystalline nature . The observed sharpness in diffraction peak confirms that grown crystals possess less solvent impurities and are free from grain boundaries . The evaluated cell parameters of grown crystal are tabulated in Table which agrees well with reported literature …”

High-end nonlinear optical devices demand superior quality KH 2 PO 4 crystal and to meet this necessity slow solvent evaporation technique is employed to grow optical quality potassium dihydrogen orthophosphate (KH 2 PO 4 , KDOP) crystal by doping tartaric acid (TA) and special attention is devoted to optimize the defect influenced properties of KDOP crystal. The incorporation of TA in KDOP crystal matrix is evaluated by employing energy dispersive spectroscopic technique. The crystalline phase and structural dimensions of pure and TA doped KDOP crystal is evaluated by means of powder X-ray diffraction analysis. The luminescence behavior of TA doped KDOP crystal is examined in visible region and violet colored emission is evidenced at 408 nm. The Vickers microhardness studies are carried out to uncover the constructive influence of TA on hardness and elastic stiffness coefficient of KDOP crystal. Impressive role of TA in minimizing defect density and improving the surface growth mechanism of KDOP crystal is explored by chemical etching analysis. The thermogravimetric analysis curve is traced within 30-650°C and TA doped KDOP crystal is found thermally stale up to 233°C. The results are appraised to propose the suitability of TA doped KDOP crystal for distinct applications.

“…The increase in dielectric constant is facilitated by the dominance of space charge polarization at lower frequency and higher temperature [36,37]. It is noticeable that doping of glycine results in decrease of dielectric constant of KDP crystal, which causes that glycine doped KDP crystal offers less power consumption, reduced Rc delay and minimum contact with adjacent connections [38] which is the most desirable parameter for fabricating THz wave generators, field detectors, photonic and electro-optic modulator devices [39]. According to Miller [40], material exhibiting lower dielectric constant offers high SHG efficiency coefficient which is in agreement with the present study.…”

Present investigation has been started to perform the comparative study of pure and glycine doped KH 2 PO 4 (KDP) single crystals grown by most commercial slow solvent evaporation technique. The grown crystals were subjected to single crystal X-ray diffraction analysis to determine their structural parameters. The linear optical studies of pure and glycine doped KDP crystal have been undertaken within 200 nm to 1100 nm wavelength range by means of UV-Vis studies. The enhancement in second harmonic generation (SHG) efficiency of glycine doped KDP crystal has been determined using a standard Kurtz-Perry powder test. The dielectric measurements have been carried out to explore the impact of glycine dopant on dielectric constant and dielectric loss of KDP crystal. The surface growth habitat and etch pit density of glycine doped KDP crystal have been evaluated using the results of microscopic etching studies. In light of obtained results the suitability of glycine doped KDP crystal for device applications has been discussed.

“…The material having lower dielectric constant has less number of dipoles per unit volume and, as a result, it will have minimum losses as compared to the material having higher dielectric constant [24]. The observed low dielectric constant at higher frequency indicates that the CCTC crystal may offer less power consumption and reduced RC delay [25] which is a prerequisite demand for designing microelectronic, THz wave generators, electro-optic modulators and field detector devices [26][27][28]. Also, a low dielectric constant is a parameter suitable for the enhancement of SHG coefficient which is in accordance with the Miller rule [29].…”

It is important to grow and characterize new bimetallic thiocyanate single crystals as they are expected to exhibit useful optical and electrical properties. In the present study, calcium cadmium thiocyanate CaCd(SCN) 4 single crystals were grown by slow evaporation of solvent and were characterized chemically, structurally, thermally, optically and electrically. X-ray diffraction analysis indicates that the grown crystal belongs to the tetragonal crystal system with lattice parameters: a = b = 12.2491(7) Å and c = 15.1012(5) Å. EDAX spectral analysis confirms the expected chemical composition. Thermogravimetric (TG/DTA) measurement implies good thermal stability. Optical (UV-Vis-NIR absorption spectral and SHG efficiency) measurements suggest good optical absorption in the UV and blue regions and the SHG efficiency of 6.13 (in urea unit). The dielectric measurements carried out in the temperature range of 40°C to 150°C at five different frequencies, viz. 100 Hz, 1 kHz, 10 kHz, 100 kHz and 1 MHz indicate a normal dielectric behavior.
