Multi-peak red fluorescence emissions in Sm 3þ -doped multicomponentalkali-alkaline-borate (MCAAB) glasses for laser-induced illumination are quantitatively characterized, revealing that the quantum yield (QY) is closely related with the wavelength of pumping sources. Under the excitation of 370 nm UVA-LED, the net emission photon numbers of 1.00 wt% Sm 2 O 3doped MCAAB glasses are derived to be 58.0 Â 10 12 cps, and the QY reaches to 25.3% which is about twice as much as 12.2% under 469 nm blue-LED pumping, which is attributed to the better excitability in UVA spectral region. In order to extend the effective excitation range to UVB, Ce 3þ is co-doped in Sm 3þ -doped MCAAB glasses as a sensitizer, which results in an enhancement of Sm 3þ excitation intensity by a maximum sensitization factor of 9.16 in the UVB region. Absolute spectral parameters under 453 nm blue laser excitation exhibit that net emission photon numbers are up to 199.4 Â 10 12 cps in 1.00 wt% Sm 2 O 3 doping case, and QY is solved to be 6.2%. Higher QY of the Sm 3þ -doped MCAAB glasses is expected to be achieved by further adopting wavelength-matched pumping laser, implying that Sm 3þ -doped MCAAB glasses is a promising candidate as high power-density light source in special laser-induced illumination.

“…Research on new optical materials for the mid-infrared region has been conducted for many years due to their potential use in applications such as atmosphere pollution monitoring, eye-safe laser radar, remote sensing, and microsurgery [1,2,3,4]. The spectral transmittance in the mid-IR region of most common optical glasses based on oxides such as phosphate (1200 cm −1 ), silicate (1100 cm −1 ), or borate (1400 cm −1 ) is limited due to their high maximum phonon energies [5,6]. On the other hand, non-oxide glasses with low phonon energy and high transparency in mid-IR are characterized by poor thermal stability which complicates processing them into photonic structures [7,8,9,10,11].…”

Bismuth-germanate glasses with low hydroxide content co-doped with Ho3+/Yb3+ ions have been investigated in terms of structural and spectroscopic properties. To reduce OH- ions content and improve transmittance value at the wavelength of 3.1 µm, the glass synthesis has been carried out in low vacuum conditions (45–65 mBar). The composition of the host glass based on heavy metal oxides affects the maximum phonon energy (hωmax = 724 cm−1), which low value has a positive impact on the mid-infrared emission parameters. Emission band at the wavelength of 2.87 µm was observed in glass co-doped with mol% 0.25 Ho2O3/0.75 Yb2O3 under 980 nm high power laser diode wavelength excitation. Lifetime measurements of the Yb3+:2F5/2 quantum level indicate efficient Yb3+ → Ho3+ energy transfer (η = 61%). The developed active bismuth-germanate glass was used as the core of optical fibre operating in the mid-infrared region.
