“…Comparing the result with the pure ADP it is found that the addition of glycine has decreased the solubility of the pure ADP. Similar results have been reported by us in ammonium acetate added ADP [12]. The solubility curve is shown in Fig.…”

“…The resistivity of the used deionized water is 18 MX-cm. The solubility of pure ADP in deionized water was reported by us [12]. In order to know the effect of glycine in solubility of ADP, the 1 mol% of glycine is dissolved fully in 100 ml deionized water and the solubility of ADP is gravimetrically analyzed using the solution.…”

“…In order to confirm the reproducibility, several times the beam was passed through the various regions of the crystals and the same results were observed. The pure ADP has 65% transmittance [12][13][14]. The large transmission in the entire visible region enables it to be a good candidate for electro-optic and NLO applications [15].…”

“…Ammonium dihydrogen phosphate (ADP) (NH 4 )H 2 PO 4 is an interesting material with varied application as a piezoelectric material in transducer devices, nonlinear optics (NLO), electro-optics, and as monochromators for X-ray fluorescence analysis [1][2][3][4][5][6]. ADP was among the first material that were used and exploited for their non-linear optical (NLO) and electro-optic (EO) properties [7].…”

Ammonium dihydrogen phosphate (ADP) (NH 4 H 2 PO 4 ) single crystals were grown by gel method using sodium metasilicate (SMS). The X-ray diffraction analysis of the as-grown ADP crystals showed that it possess tetragonal structure having lattice parameters a = 7.502 °A and c = 7.554 °A. The Fourier transform infrared spectroscopy (FTIR) of as-grown ADP crystal taken between wave-number 400 to 4000 cm -1 showed peaks due to vibration and stretching of functional group O-N=P and -ONO 2 in 485 to 902 cm -1 , P=O and O-H in 1076 to 1544 cm -1 and O-H and N-H in 2400 to 3371 cm -1 range. The UV-Vis-NIR spectroscopy of ADP crystal showed direct optical bandgap of 4.99eV and indirect optical bandgap of 4.12eV. The optical microscopy employed to study the surface microstructure showed hillocks on the as-grown surfaces arising due to local increased supersaturation. The thermal properties of the as-grown ADP crystals were studied by thermogravimetric analysis (TGA). The thermal activation energy determined from the TGA curve using Broido, Piloyan-Novikova (PN) and Coats Redfern (CR) relations were in good agreement with each other. The obtained results are discussed in details.

Herein, ammonium dihydrogen phosphate (NH 4 H 2 PO 4 , ADP) crystals were grown in a defined crystallographic direction (q ¼ 90 , F ¼ 45 ) in an aqueous solution using the point seed rapid growth method. Ex situ atomic microscopy (AFM) measurements were implemented to observe the prismatic growth micro-morphology of ADP and Cr 3+-doped ADP in the defined crystallographic direction. It was found that with the increasing supersaturation, the growth morphology changed in turn to elementary steps, macro steps, and 2D nuclei. Moreover, the differences between ADP and Cr 3+-doped ADP grown in the defined crystallographic direction have been discussed. The influence of Cr 3+ on the growth of ADP crystals has been explored.
