Er:YScO3 mixed sesquioxide crystal fibers grown by the LHPG technique and optical characterization

Erbium-doped YScO₃ mixed sesquioxide crystal fibers with doping concentrations of 1 at.%, 4 at.%, and 7 at.% were grown using the laser-heated pedestal growth (LHPG) method. The spectral properties of Er:YScO₃ were investigated, revealing an absorption cross-section of 2.05 × 10⁻²¹ cm² at 983 nm with full width at half maximum (FWHM) of 20.7 nm for 7 at.% Er:YScO₃ crystal fiber. The Judd-Ofelt parameters (Ω₂ = 1.50 × 10⁻²⁰ cm², Ω₄ = 0.66 × 10⁻²⁰ cm², Ω₆ = 0.96 × 10⁻²⁰ cm²) were derived, and the emission cross-section at 2729 nm was calculated to be 0.53 × 10⁻²⁰ cm² with FWHM of 65.0 nm. The fluorescence lifetimes of the ⁴I_11/2 and ⁴I_13/2 levels were analyzed across doping concentration. The results demonstrate the potential of Er:YScO₃ crystal fibers as a promising gain medium for ∼2.7 μm laser applications.

期刊介绍： The purpose of the Journal of Luminescence is to provide a means of communication between scientists in different disciplines who share a common interest in the electronic excited states of molecular, ionic and covalent systems, whether crystalline, amorphous, or liquid. We invite original papers and reviews on such subjects as: exciton and polariton dynamics, dynamics of localized excited states, energy and charge transport in ordered and disordered systems, radiative and non-radiative recombination, relaxation processes, vibronic interactions in electronic excited states, photochemistry in condensed systems, excited state resonance, double resonance, spin dynamics, selective excitation spectroscopy, hole burning, coherent processes in excited states, (e.g. coherent optical transients, photon echoes, transient gratings), multiphoton processes, optical bistability, photochromism, and new techniques for the study of excited states. This list is not intended to be exhaustive. Papers in the traditional areas of optical spectroscopy (absorption, MCD, luminescence, Raman scattering) are welcome. Papers on applications (phosphors, scintillators, electro- and cathodo-luminescence, radiography, bioimaging, solar energy, energy conversion, etc.) are also welcome if they present results of scientific, rather than only technological interest. However, papers containing purely theoretical results, not related to phenomena in the excited states, as well as papers using luminescence spectroscopy to perform routine analytical chemistry or biochemistry procedures, are outside the scope of the journal. Some exceptions will be possible at the discretion of the editors.
