“…As a result the crystal has high optical transmission in the optical region, which is an essential requirement for a non linear optical material for SHG. Our results resembles with the earlier reported results in case of other crystals [16,17]. The frequency dependent dielectric behavior of the PTI crystal is due to the contribution of electronic, ionic, dipolar and space-charge polarizations [17,18].…”

“…A similar behavior has earlier been reported in the case of other crystals by many researchers that dielectric loss decreased as the frequency of the applied field increased [17,19]. This small value of dielectric loss indicates that the grown crystal possesses enhanced optical quality with less defects, which is of high importance for applications in NLO materials [16]. Moreover, there is no significant effect of temperature on tand which has been observed for all the frequencies.…”

A desirable quality bulk single crystal of a novel organometalic nonlinear optical material of potassium thiourea iodide measuring 20 9 10 9 6 mm 3 have been grown successfully from solution by slow evaporation method. The solubility curve of this material has been determined in double distilled water which is the most suitable solvent. The diffraction curve by HRXRD method corresponds to (531) plane of the tetragonal crystal. This paper reports vacancy type of point defects in the grown crystal by high resolution XRD method. Entrapped impurities during the crystal growth process are also reported. A stable-small and nearly same value of dielectric loss at four different temperatures in the high frequency range indicates comparatively better quality assessment of the grown crystal. Powder XRD and a.c. conductivity measurements are also carried out. The results of dielectric studies at four different temperatures indicate that the grown crystal is a promising optical material for photo induced second harmonic generation in laser physics.

“…The excellent nonlinear properties of LAP analogs make them potential candidates to replace KDP for frequency conversion of infrared lasers. In the earlier attempts, our research group has reported on the growth and characterization of LADP, LADN, LADI, LAF and LAHF-the analogs of LAP [5][6][7][8][9].…”

“…6. From the curves it is clear that the dielectric loss values are high at lower frequencies and starts decreasing gradually for higher frequency.Hence the gradual decreases of dielectric constant as well as the dielectric loss at higher frequency suggest that the crystal possesses enhanced optical quality with lesser defects which is an important parameter of the nonlinear optical materialsin their high speed electro-optic modulation [10].…”

Semi organic single crystal of guanidinium cobalt sulphateheptahydratewas grown from its aqueous solution by slow evaporation solution growth technique. Powder X-ray diffraction analysis (PXRD) was carried out to confirm the formation of the crystalline compound. The functional groups present in the crystal were identified by FTIR spectroscopic analysis.Thermo gravimetric and differential thermo gravimetric analyses (TG-DTG) were performed to analyse the thermal behaviour of the grown crystal. The dielectric constant and dielectric loss of the grown crystal were studied as a function of frequency of the applied field. The ferroelectric nature of the grown crystal was analysed by P-E hysteresis loop.
