The production and thermal decay of point defects in undoped single crystals of KD 2PO 4 were characterized using optical absorption and electron paramagnetic resonance (EPR) techniques. X-ray irradiation was performed on crystal at 77 K, followed by warming upto room temperature. Broad optical absorption were observed to peak near 230, 390, and 550 nm after x-ray irradiation. Result show that the band at 230 nm is associated with interstitial deuterium atoms, the two bands at 390 and 550 nm are associated with self-trapped holes.
