Effect of Al3+ ions on the optical quality, growth rate, shape, and structure of potassium dihydrogen phosphate (KDP) crystal was investigated. Growth method was based on the “point seed” method in a solution with optimum concentration, following spontaneous growth at room temperature. FTIR spectrum showed neutralization of O-H group in KDP crystal by Al3+ ions. UV-Visible spectrum of the crystal containing Al3+ displayed an undesirable increase of the optical absorption in the 200-300 nm region with a maximum at 270 nm. It seems that the absorption in the 200-300 nm region is due to substitution of phosphorus by Al ions. In fact, (AlO4)2- ions are present in the KDP crystals and give rise to ultraviolet absorption.
