title = "Thermal transport and optical spectroscopy in 710-MeV Bi ion irradiated LiF crystals",
abstract = "We present thermal conductivity measurements of lithium fluoride single crystals irradiated by 710 MeV Bi ions at fluences ranging between 1010 and 1013 cm−2. The thermal transport degradation due to irradiation damage was examined across two depths regions, on nanometer and micrometer scales, by picosecond time-domain thermoreflectance and modulated continuum wave thermoreflectance methods, respectively. The proliferation of swift heavy ion-induced structural defects (color centers) was characterized using optical absorption and photoluminescence spectroscopies. Klemens thermal model was applied to correlate the concentrations of color center defects to thermal conductivity reduction in irradiated LiF crystals.",
