“…The values of the decay components obtained from the fitted curve are 1 ¼ 3:67 ms, 2 ¼ 1:80 ms and 3 ¼ 6:60 ms. Thereby, we can deduce their nature as shallow and deep defects (Khan et al, 2008;Thukral et al, 2014;Vijayan et al, 2014). The residuals shown in the inset of Fig.…”

“…TRPL is a powerful tool used for the optical characterization of semiorganic single crystals. It is an eminent nondestructive technique to check the optical characterization of crystals with emphasis on the excitation dynamics (Vijayan et al, 2014). Moreover, it highlights the crystalline quality of the single crystal, allowing us to design optimal device performance by calculating the excitation lifetimes.…”

To achieve good quality bulk size crystal growth, an assessment of the nucleation kinetics of a semi‐organic L‐leucine hydrobromide (L‐LHBr) crystal was carried out using double‐distilled water as solvent medium. The effect on metastable zone width (MSZW) with increasing temperature and on induction period with varied supersaturation level was determined experimentally and was found to be very well in accordance with the nucleation theory prospects. Thereafter, various other nucleation parameters, such as Gibbs free energy and interfacial energy, were also determined. The knowledge of these nucleation parameters indicated the requisite temperature domain and the appropriate growth technique, leading to the successful single‐crystal growth of L‐LHBr by slow cooling in the temperature range 298–291 K. The cooling rate of 0.25 K per day was optimized after repeated trials. X‐ray diffraction and Raman analysis were performed on grown crystals for the verification of the material. High‐resolution X‐ray diffraction analysis was used to assess the crystalline perfection of the grown crystals. To further explore the properties of the grown crystals, photoluminescence and time decay studies, etching analysis, and Z‐scan measurements were performed.

“…It is a non-destructive technique can be used to know quality of material as exciton life time varies with crystal nature and its defects concentration. The decay time of a particular transition strongly affects the efficiency of radiative recombination [18]. The decay of PL emission has been recorded at nanosecond scale at room temperature as shown in figure 6 which generally having multi-exponential process with a series of short and long decay components.…”

A good optical quality semi-organic single crystal of Potassium Acid Phthalate (KAP) was harvested from aqueous solution by using slow evaporation solution growth technique (SEST) at ambient condition. The defect free single crystal of KAP was analyzed by different instrumentation techniques, for checking its compatibility for different applications. Its unit cell dimensions and phase purity was examined by powder X-ray diffraction (PXRD) and found that it crystallizes in orthorhombic with non-centrosymmetric in nature. The quality of the grown ingot was assessed by high resolution X-ray diffraction (HRXRD) technique and found that, the crystalline quality is better with less grain boundaries. Its optical properties were scrutinized by UV-vis., photoluminescence (PL) and time resolved photoluminescence (TRPL) measurements respectively. The mechanical stability of the grown crystal was tested by Vickers microhardness method and found that the grown crystal shows indentation size effect (ISE) which was explained using different theoretical models. Its third order nonlinear optical properties were studied by Z-scan measurement by using Ti:Sapphire laser as a source and determined its nonlinear absorption coefficient (β) and it was found that the KAP crystal is one of the preferable choices for optical limiting applications.

“…Generally, the PL decay is a multiexponential process. However, an exponential fit to the decay profile of the SA single crystal shows that the curve has biexponential nature (Vijayan et al, 2014) and can be analysed approximately as two 'exponential' components, as given in the equation below:…”

A bulk sulphamic acid single crystal has been grown by a modified seed rotation technique. The lattice dimensions of the grown single crystal were confirmed using powder X-ray diffraction, and it was found that it crystallized in an orthorhombic structure with space groupPbca. The strain in the lattice was calculated by the Williamson–Hall equation. The crystalline perfection was examined by high-resolution X-ray diffraction and found to be extremely good (the single peak of the rocking curve having an FWHM of ∼8.0′′). The luminescence behaviour was recorded in the wavelength region between 400 and 630 nm using an Xe flash lamp which acts as an excitation source. The shock damage threshold was measured for the grown crystal in order to determine the mechanical capability of the title compound. The thermal parameter of sulphamic acid was calculated by photoacoustic spectroscopy.
