Thermal history of LiF single crystals during neutron irradiation

Influence of Neutron Irradiation Conditions on Maximal Frequency of IR Absorption Spectra of LiF:OH Single Crystal

“…[15] Irradiation of LiF with ionizing radiation-X-rays, electrons, ions, extreme UV light, etc.-causes the stable formation of primary and aggregate point defects. [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31] Aggregate F 2 and F 3 þ color centers -two electrons bound to two and three close anion vacancies, respectively-feature visible Stokes-shifted emission in the red (F 2 ) and green (F 3 þ ). [32] As it is well known, the same color center F 2 , F 3 þ (Table 2) are produced in LiF under thermal neutron and γ-ray irradiation at room temperature.…”
