Abstract:

Cathodoluminescence (CL) of monoclinic LiAF crystals was studied in the spectral (150-600 nm) and temperature (78-302 K) ranges using both the steady-state CL and pulse CL (PCL) techniques. Three CL emission bands were found in the spectral range of 150-600 nm. The dominant complex CL band at 350 nm obeys the Mott law (E = 0.072 eV and omega = 750). On heating, the 172 and 208-212 nm CL bands vary in intensity non-monotonically. At T = 78 K, the CL decay kinetics comprises three components: a dominant fast exponential component with a lifetime of 750 ns, and two low-intensity components with the lifetimes of 20 and 240 is. The last two components were fitted by a second order hyperbolic law. Time-resolved PCL spectra were recorded using time-windows corresponding to the PCL decay components. Paper discusses the reasonable interpretation of the CL emission bands. (C) 2015 Elsevier Ltd. All rights reserved.
