Bulk growth, crystalline perfection and optical characteristics of inversely soluble lithium sulfate monohydrate single crystals grown by the conventional solvent evaporation and modified Sankaranarayanan–Ramasamy method

Abstract: Good quality bulk size single crystals of inverse soluble lithium sulphate monohydrate (LSMH) have been grown by the modified Sankaranarayanan-Ramasamy (SR) method. A growth rate as high as 3 mm per day has been obtained for LSMH growth without substantially degrading the optical quality. The rocking curve recorded using the high resolution X-ray diffraction (HRXRD) technique reveals that the crystals grown by this method have a high degree of crystalline perfection. The optical quality of the crystals was stu… Show more

“…Usually, PL emission is attributed to three different physical bases: self-trapped excitons, vacancies, and surface states (defect). [48][49][50] In addition, when we further excited our Eu 3+ doped crystal by 393 nm wavelength photons, the same emission peaks with the comparatively small intensity we observed. It seems the quantum yield enhances when excited the sample with higher energy photon (more or exactly its CTB).…”

“…Theoretical calculations were executed to give an insight into the electronic structures of the title compound. As shown in Figure S7, the calculated band gap of Hg 3 (SeO 3 ) 2 (SO 4 ) is 3.94 eV, which is smaller than the experimental value because the calculation of GGA–PBE underestimates the band gap . Therefore, the scissors value of 0.76 eV was used for the optical calculation of the compound.…”

“…The frequency doubled laser emission at λ = 532 nm, with a pulse width of 30 ps was generated by a high-quality KTP crystal, with a lens focal length of about 30 cm. Using open-aperture Z-scan measurements [16,17], the nonlinear absorption characteristics at λ = 1064 nm and 532 nm were investigated in detail. For each sample, several experiments were carried out by changing the sample location to ensure the existence and accuracy of the nonlinear absorption effect.…”
