PL Wieloskładnikowe szkła fluoroindowe są obiecującym materiałem do otrzymywania włókien optycznych mających zastosowanie w zakresie średniej podczerwieni. W wyniku aktywowania szkieł jonami ziem rzadkich stają się przydatne w konstrukcji lasera niebieskiego, konwertora promieniowania podczerwonego na [...]
EN Multicomponent fluoroindate glasses are promising materials for ultra-low loss mid-infrared optical fibers. Upon doping with rare earth ions, fibers are suitable for the development of blue lasers, tunable lasers, up-conversion lasers, high power laser materials and optical amplifiers for telecommun[...]

EN Heavy metal oxide and oxyfluoride lead silicate glasses doped with rare-earth ions were prepared. Next, they were heat treated in order to obtain transparent glass-ceramics. The rare-earths as optically active ions were limited to trivalent Eu3+ and Dy3+. Correlation between the local structure and [...]

EN Heavy metal lead borate glasses doped with rare earth ions were examined. The influence of heavy metal oxide PbO and activator concentration on luminescence properties of rare earth ions are discussed. Rare earth ions were limited to Eu3+, Dy3+ and Tb3+ which are emitting in the visible light. Incre[...]

EN Erbium-doped lead silicate glass has been investigated for near-infrared emission and up-conversion applications. Near-infrared emission due to 4I13/2→4I15/2 transition of Er3+ is relatively broad (70.5 nm) and long-lived (3.7 ms). Also, up-conversion luminescence spectra of Er3+ ions in lead silica[...]

EN Oxyfluoride lead borate glasses singly doped with Nd3+ and Er3+ ions have been studied before and after thermal treatment. The orthorhombic PbF2 crystallites are formed during thermal treatment, which was evidenced by X-ray diffraction analysis. Near-infrared luminescence spectra at 1.06 žm and 1.53[...]

PL W pracy przedstawiono właściwości strukturalne i optyczne szkieł ołowiowo-boranowych o różnej zawartości w składzie tlenku ołowiu do tlenku boru. Badania przeprowadzono z zastosowaniem dyfrakcji rentgenowskiej, spektroskopii w podczerwieni i absorpcji światła. Ze wzrostem stężenia tlenku ołowiu prz[...]
EN Structural and optical properties of lead borate systems with various PbO/B2O3 ratio in glass composition have been studied using X-ray diffraction, optical absorption and infrared spectroscopy. Increase of lead oxide concentration shifts light transparency in the direction of the longer wavelengths[...]

EN Energy transfer processes in lead borate glasses doubly doped with Yb-Tm and Yb-Er have been investigated at room temperature under excitation of Yb at 975 nm. The non-resonant energy transfer from 2F5/2 state of Yb to 3H5 state of Tm results in up-converted emission at 850 nm due to the 3H4-3H6 tra[...]

EN Oxyhalide lead borate glasses doped with rare earth ions have been studied before and after thermal treatment. The rare earths as optically active ions were limited to the Er3+ ions. Near-infrared luminescence due to the main 4I13/2–4I15/2 laser transition of Er3+ was registered. The introduction of[...]

EN Results of X-ray diffraction (XRD), differential scanning calorymetry (DSC), electron probe microanalysis (EPMA) and optical absorption of InF3-based glasses are reported. Different concentrations of rare earth ions have been added to a base glass. XRD results show that no crystalline phases are for[...]

EN Multicomponent indium based fluoride glass singly doped with europium, terbium, holmium and thulium has been investigated using methods of optical spectroscopy. Owing to low energy of phonons available in the glass matrix, the luminescent levels of rare earth ions are depopulated mainly by radiative[...]
