Optical properties of UV-induced color centers in a KY3F10:Ce3+ crystal
The evolution of color centers induced in a KY 3 F 10 :Ce 3+ crystal by UV radiation has been observed and interpreted. It has been revealed that, initially, the UV irradiation of the KY 3 F 10 :Ce 3+ crystal induces the formation of color centers predominantly of the F -type, which, in a short time...

crystal induces the formation of color centers predominantly of the
F
-type, which, in a short time period of about ten minutes, are transformed into complex color centers of the

-type, as well as into impurity color centers. Based on the data obtained, a diagram of energy states of the crystal, dopant, and color centers has been constructed, on which most probable processes that are caused by electronic transitions occurring in the KYF:Ce
3+
crystal after its UV irradiation have been indicated. |
