Growth and Studies of Strontium Chloride Doped Ammonium Dihydrogen Phosphate Crystals

Single crystals of undoped ammonium dihydrogen phosphate (ADP) and strontium chloride doped ammonium dihydrogen phosphate were grown by a solution method. It is found that SCADP crystal belongs to the tetragonal crystal system with I-42d space group. It is seen that both undoped and strontium chloride doped ADP crystals crystallize in the same tetragonal system and the incorporation of dopant does not alter the crystal system. This is due to the presence of dopant strontium chloride in the form of metal ions and halogen ions in the interstitial positions of the lattice of the host ADP crystal. Structural studies of the grown crystals were carried out to find the crystal structure and due to doping of strontium chloride, the structure of the doped ADP crystal was not altered. Microhardness studies of the grown crystals of undoped and strontium chloride doped ADP crystals were done to understand the mechanical strength. The second order and third order NLO studies of the samples were carried out to obtain the NLO properties. Spectroscopic studies like FTIR studies, EDAX studies and UV-visible spectral studies were carried out for the grown crystals. Also thermal and LDT studies were performed for the characterization of the prepared samples.
