Abstract
In this paper the results of optical absorption study on the annealing behavior of alkali colloids in KCl:Na crystals were presented. It is found that the sodium colloids were formed in the crystals during the annealing treatment, instead of the potassium colloids. The absorption properties of these sodium colloids were observed, and show that the states of the colloids are dependent on the annealing treatment that include three factors: (a) the time of annealing treatment, (b) the temperature of annealing treatment and (c) the process of annealing treatment. To discriminate the F-band and colloids-band, the emission spectra were also measured in some cases.
