“…The changes in the hardness value due the addition of amino acid may be due to the interaction between O-H group of KAP with COO group of amino acid. Higher the hardness values greater is the stress required to form dislocation, thus confirming greater crystalline perfection especially for the lower concentrated aspartic acid/L-citrulline doped crystals 12 . The well known Meyers relation is stated as P=K 1 d n Where, K 1 is the standard hardness value (material constant) and n is the work hardening coefficient (Meyers index number).…”

Potassium acid phthalate (KAP) is an interesting semi-organic optical material. Optically transparent good quality single crystals of pure and amino acid added KAP single crystals were grown by conventional slow evaporation technique at 32 o C and characterized to study the thermal and mechanical stability of the crystal. The x-ray diffraction analysis confirms the presence of amino acid molecules in the KAP crystal matrix in the case of amino acid added KAP single crystals. The thermogravimetric (TG/DTG) and microhardness measurements indicate that the amino acid addition significantly tunes the thermal stability and mechanical strength of the KAP crystal.

“…Pure NaAP crystal has 60% transmittance while LHMHC dihydrate doped NaAP crystal has 80% transmittance in the entire UV-Visible region. The obtained results were compared with the reported work [9] and it was observed that LHMHC dihydrate doped NaAP crystal show better optical transmittance value than L-Valine doped NaAP crystal in the entire visible region. The increment in the optical transmittance of LHMHC dihydrate doped NaAP crystal compared to pure NaAP one suggests the enhancement in optical quality.…”

The pure and semiorganic material of L-Histidine monohydrochloride dihydrate (LHMHC dihydrate) doped sodium acid phthalate (NaAP) single crystals were effectively grown from deionized water by slow evaporation solution technique. Single crystal X-ray diffraction is employed to know the precise information about the crystallographic structure and also the title materials are orthorhombic crystal system with space group B2ab. The interaction of various functional groups was recognized by FT-IR spectral study. The title materials are optically transparent and having a lower cut-off wavelength as 300 nm, thereby confirming the enhancement of nonlinear optical property and optical band gap of the pure and LHMHC dihydrate doped NaAP crystals have been determined as 3.5 eV and 4 eV by UV-Visible studies. The dielectric constant and dielectric loss of the pure and LHMHC dihydrate doped NaAP crystals decrease as the frequency of applied field increases at the end. The mechanical behaviors of the grown crystals were assessed by Vickers microhardness activities. The SHG efficiency of the grown crystals confirms NLO behavior of green colour emission to offer frequency doubling process for photoelectronic applications.

“…There have been many nonlinear materials synthesized in the last decade that include both organic and inorganic compounds. Although they had to overcome problems related to a low laser damage threshold, inadequate optical transmittance, and poor optical precision, their system applications have been hindered by these problems [12]. Because of the hydrogen bonding, pure organic crystals have lower mechanical robustness.…”

The slow evaporation technique was used to successfully grown amino acid doped sodium acid phthalate (NaAP) crystals at room temperature. A great deal of research has been done on the effects of amino acids on NaAP growth and characteristics. X-ray diffraction was used to examine the crystal structure and lattice parameters of the grown crystals. Functional groups were found in the title crystals, which revealed themselves utilizing FTIR spectra. The optical transparency of the doped crystals was noticed by measurements of optical absorption. In order to assess the mechanical strength of the produced crystals, Vickers microhardness tests were employed. The technique of Kurtz powder was utilized to calculate the second harmonic generation (SHG) performance of the cultivated crystals.
