摘要：

The luminescent characteristics in the visible and near infrared spectral ranges of both pure MeF2 fluoride crystals (Me = Ba, Ca and Sr) and those doped with Er3+ ions, which are implanted with high-energy (similar to 100 keV) silver ions are studied. It is found that in the former case, a thin surface layer of the irradiated crystals emit a composite band in the spectral range of 450-1000 nm (lambda(exc) = 405 nm), caused by the luminescence of the formed silver nanoparticles. In the latter case, only the luminescence bands of Er3+ ions are recorded, the intensity of which are enhanced significantly (for instance, up to near 4 times for CaF2:Er3+ sample) compared to the virgin, i.e. non-irradiated, samples. This is experimental evidence in favor of the fact that the observed increase in the luminescence of Er3+ ions is due to non-radiative energy transfer to them from excited silver NPs, which form a layer about 100 nm thick in the irradiated crystal.
