Single crystals of pure, hydrogen borate and potassium nitrate doped Ammonium Dihydrogen Phosphate (ADP) were grown from aqueous solutions, employing slow evaporation technique at room temperature. The grown crystals were subjected to powder X–ray diffraction studies to study their structural characteristics. FTIR spectral analysis was performed to identify the presence of various functional groups in the crystals. The UV–Visible–NIR spectral analysis was carried out to confirm the improvement in the transparency of the ADP crystal on the addition of boric acid and potassium nitrate.
