Abstract Gamma-irradiation of KF. 2H2O and KF. 4H2O crystalline hydrates at low temperatures results in the appearance of colour centres. The characteristics of optical spectra of these centres at 77 °K are: λmax = 475 nm and W 1/2 = 0.58 eV for KF. 2H2O; λmax = 480–485 nm and W1/2 = 0.62 eV for KF. 4H2O. The EPR spectrum of colour centres is an isotropic singlet with g-factor 2.001 and ΔH = 34.5 Oe (for KF. 2H2O at 77 °K). Their yields are low (0.015 and 0.0055 particles/100 eV for KF. 2H2O… CONTINUE READING
