Gamma irradiation effect on optical and dielectric properties of potassium dihydrogen phosphate crystals

Study on the defects of KDP crystal with different states by the positron spectroscopy method

“…Accordingly, the intensity I 1 represents the relative concentration of defects. 20 The second lifetime τ 2 indicated information about vacancy-type defects, such as potassium vacancy, impurity displacement, and complex defects. Similarly, the relative size of the defect was relevant to the annihilation lifetime with the relative concentration of defects corresponding to the intensity I 2 .…”

“…The positron annihilation technology could identify the size and concentration of the defects by detecting the positron lifetime caused by the electron density change at a specific position. 20 The S – E diagram of a slow positron–electron beam could characterize the defects' overall distribution with the positron incidence depth. Thus, it could be applied to KDP and ADP crystals to detect the types and distributions of the different concentrations of Fe 3+ defects.…”

Effect of gamma-irradiation on the properties of aluminum dihydrogen triphosphate

“…A further reason for using gamma irradiation is its unique application in the modification of materials. [10][11][12][13] Gamma irradiation is a kind of green processing technology and an effective surface modification method with potential application prospects. However, the effect of gamma irradiation on ADTP was rarely reported in the relevant literature.…”
