“…1 shows the IR transmission spectra of QG and BCM in the frequency range 8000−4000 cm −1 depending on the chemical composition of the PG-matrix (PG 8V-NT or PG-NFF) and the sintering atmosphere (nitrogen, argon). The table shows the absorption bands found in QG 8V-NT, QG-NFF and BCM in comparison with the previously obtained data [25,26].…”

The spectral-optical and luminescence properties of bismuth-containing composite materials based on matrices of high-silica porous glasses are investigated. Luminescence spectra, luminescence excitation spectra, infrared transmission spectra (8000-4000 cm-1) depending on the composition of different types of matrices and sintering atmosphere (nitrogen, argon) of bismuth-containing composite materials were examined. It was found that the samples of bismuth-containing composite materials are characterized by UV (λem=350 nm), blue-green (λem=410-550 nm) and orange-red (λem=600-725 nm) luminescence due to the presence of various bismuth active centers. The analysis of the spectra obtained by near-infrared spectroscopy demonstrates the formation of Bi2+ dimers of bismuth and bismuth active centers associated with silicon. Keywords: Bismuth-containing composite materials, high-silica porous glass, near-infrared spectroscopy, luminescence, bismuth active centers.

“…It considers the amount of energy, pays more attention to animation quality, and pursues the best energy level match, revealing more deeply. The nature of energy degradation and the causes and locations of various losses in the process of energy transfer and conversion indicate the direction for the rational use of energy [6]. The exergy analysis method has been proven to be the most effective energy analysis method.…”

Chinese heating method has gradually shifted from small fragments to centralized regional heating. This heating method has achieved obvious energy-saving benefits. The article establishes an economic model of the energy utilization rate of the central heating system and installs the system exergy balance equation at the same time. The simulation found that the energy utilization coefficient of the heating system is high and has a high energy-saving potential. The effect of energy utilization is poor, and it has great potential for energy saving.

Bismuth-doped phosphosilicate fibers have become the most promising gain medium for O-band amplifiers. Yet scientific challenges on understanding the nature of bismuth active centers (BACs), mechanisms of bismuth cluster formation in the phosphosilicate glass network still exist. It is likely that multiple BACs with different oxidation states in different structural sites all contribute to the broad, nonsymmetric luminescence and gain spectra. Due to the progress in the fundamental understanding of bismuth-doped phosphosilicate glass, various designs of optical amplifiers with decent performances have been demonstrated.
