Seedlings of Scots pine (Pinussylvestris L.) were artificially frost hardened under controlled conditions. To follow the development of hardiness, the frost killing temperature was determined. Four levels of hardiness were defined during the course of frost hardening. After adaptation of the seedlings to dark conditions at room temperature, fluorescence induction and far red induced luminescence decay kinetics were recorded for seedlings of the four defined levels of hardiness. The induction curve of fluorescence and the decay curve of luminescence were digitized for 110 time intervals, and the values were used in a multivariate partial least squares analysis to evaluate the potential of luminescence and fluorescence as predictive probes for cold hardiness. The results showed that both fluorescence induction and luminescence decay kinetics contain information allowing the prediction of frost hardiness of artificially cold-hardened seedlings of Scots pine.

Er3+ doped lead-halide crystals perform a number of properties which make them perspective for practical use in waveguides and spectrum converters. In current work we have studied luminescence spectra dependencies over the excitation wavelength, luminescence intensity dependences over temperature for up-conversion excitation of most significant lines (530, 550 and 650 nm) under 980 nm excitation. Luminescence decay kinetics under 313 nm and 365 nm excitation in KPb2Cl5:Er3+, RbPb2Br5:Er3+ и KPb2Cl5:Er3++Yb3+ have been measured and theoretical estimates of the lifetimes were made in accordance with Judd-Ofelt technique. Received results can be used in laser systems design and for accuracy evaluation when Judd-Ofelt technique for these crystals is applied.

ABS – BGP (Al2O3 – B2O3 – SiO2 – BaCO3 – Gd2O43 – P2O5) glasses doped with different Ce3+ concentrations were prepared by glass melting method. Optical, structural and luminescent properties have been characterized. Emission in the spectral range of 350–550 nm, associated with radiation transitions of Ce3+ ions was recorded. The luminescence decay kinetics is characterized by two components. The fast component is 45–90 ns. For the slow component, a decrease in the decay time from 4 to 0.9 us with increasing cerium ion concentration is shown. Based on the luminescence spectra, an assumption about the existence of various emitting states of the Ce3 + ion in borosilicate glass was made.
