Complex F-aggregate centers were studied in pure and Li+-doped KF, by means of optical excitation. Three new emission bands in the near infrared region were revealed. Among them, the luminescence at 1040 nm was identified as the emission of F3 defects because of its excitation, its peak position and its enhancement under irradiation at room temperature with F light. The luminescences at 950 and at 1250 nm were too weak and could not be unambiguously identified. However, they are probably due to complex F-aggregate centers, like F4 defects.

Abstract

Complex F-aggregate centers were studied in pure and Li+-doped KF, by means of optical excitation. Three new emission bands in the near infrared region were revealed. Among them, the luminescence at 1040 nm was identified as the emission of F3 defects because of its excitation, its peak position and its enhancement under irradiation at room temperature with F light. The luminescences at 950 and at 1250 nm were too weak and could not be unambiguously identified. However, they are probably due to complex F-aggregate centers, like F4 defects.
