Abstract
F(A) centers in KF:Na+(0.25%) under excitation in the absorption band produce at LHeT an emission peaking at 0.92 mum, and at LNT and higher temperatures another emission peaking at 2.10 mum. This result sugges ts that there is a temperature activated process between two different relaxed excited states.
