Abstract

The organic dyes (Amaranth, Rhodamine and Methyl Orange) were introduced in Potassium Dihydrogen Phosphate (KDP) crystals. Influences of super saturation and dye concentration in the solution, on the color and crystal habit of KDP, were observed. The highly super saturated solutions produce entirely colored crystals. The concentration of dopants in the mother solution was varied from 0.1 mole/L to 10-mole/L. The studies on pure and doped KDP crystals clearly indicate the effect of dopants on the crystal structure, in the absorption of IR frequencies and the non-linear optical property. The frequencies with their relative intensities are obtained in FT-IR of pure and doped KDP. The very weak bands for dopants indicate its presence in low concentration. This letter reports room temperature MeV Li+ ion irradiation induced depletion of hydrogen from single crystalline Potassium Dihydrogen Phosphate, which has wide applications as a non linear optical material in optoelectronics technology. Irradiations have been performed using 50 MeV Li+ ions up to a maximum dose of 2.4 × 1015 ions/cm2. Simultaneously, by detecting the elastically recoiled Li atoms allows to recover the hydrogen profile. A possible explanation of these phenomena is suggested.
