Bleaching with the F-light at the excitation bandpass of 20 nm results in the phenomenon that F-centre peak and thermoluminescence (TL) glow peaks due to Fz- and F-centres identically decrease with the F-bleach time. whereas TL glow peak due to Fz-centre only remains almost constant irrespective of its time in the case of that at the excitation bandpass of 5 nm.
