“…The rapid development of optical telecommunications requires the broadening of the near-IR range for erbium-doped fiber amplifiers (EDFA), in which signal transmission occurs at about 1500 nm. In fact, the EDFA systems based on silicate glasses [ 41 , 42 ] exhibit relatively narrow bandwidth, which contributes to the limited near-infrared broadband transmission. For that reason, many precursor glass systems singly doped with Er 3+ and co-doped with Yb 3+ /Er 3+ are still tested and selected in order to obtain enhanced near-IR luminescence in the so-called third telecommunication window.…”

Inorganic glasses co-doped with rare-earth ions have a key potential application value in the field of optical communications. In this paper, we have fabricated and then characterized multicomponent TiO2-modified germanate glasses co-doped with Yb3+/Ln3+ (Ln = Pr, Er, Tm, Ho) with excellent spectroscopic properties. Glass systems were directly excited at 980 nm (the 2F7/2 → 2F5/2 transition of Yb3+). We demonstrated that the introduction of TiO2 is a promising option to significantly enhance the main near-infrared luminescence bands located at the optical telecommunication window at 1.3 μm (Pr3+: 1G4 → 3H5), 1.5 μm (Er3+: 4I13/2 → 4I15/2), 1.8 μm (Tm3+: 3F4 → 3H6) and 2.0 μm (Ho3+: 5I7 → 7I8). Based on the lifetime values, the energy transfer efficiencies (ηET) were estimated. The values of ηET are changed from 31% for Yb3+/Ho3+ glass to nearly 53% for Yb3+/Pr3+ glass. The investigations show that obtained titanate–germanate glass is an interesting type of special glasses integrating luminescence properties and spectroscopic parameters, which may be a promising candidate for application in laser sources emitting radiation and broadband tunable amplifiers operating in the near-infrared range.

“…The past decades have witnessed the blossom of rare earth (RE) ion doped upconversion (UC) materials due to their vast practical applications in the field of solid state lasers, UC lasers, waveguide lasers, Er 3+ -doped fiber amplifiers (EDFAs), light emitting diodes (LEDs), phosphor inkjet printing, luminescent solar concentrators and optical sensing. [1][2][3][4][5] Since REincorporated oxyfluoride glass-ceramics (OxGCs) were reported by Wang and Ohwaki, 6 these luminescent glass-ceramics (GCs) were widely researched in the past as a potential optical material. In the present day, the glass matrix is preferred over the crystalline matrix for lanthanide doping because of the ease of synthesis in different shapes and sizes with uniform distribution of RE ion concentration and is suitable for devel-oping low-loss, high-strength and low-cost optical fibers.…”

“…The PL band centered at 580 nm exhibits a consistent lifetime in the order of microseconds for both films, resulting from the interaction between Er 3+ ions and the SiC x O y matrix. 47 Further analysis of the spectra reveals that the lifetimes of Er 3+ ions in the 4 I 13/2 state decrease as the concentration of Er 3+ ions increases. This reduction in lifetime, coupled with higher Er 3+ ion concentrations, can be attributed to nonradiative (NR) energy migration among neighboring Er 3+ ions and the presence of quenching centers such as OH − groups within the matrix.…”

This research paper presents findings on the properties of erbium ions incorporated within an amorphous silicon oxycarbide host matrix. A special analysis is made on photoluminescence emission. The experimental samples were prepared using tetraethoxysilane and erbium oxide as reagents via Catalytic chemical vapor deposition. Notably, a unique preparation method was employed for thin films obtention, avoiding plasma damage, which had not been utilized for this purpose previously. One of the most important accomplishments of this study consists in achieving a broad band PL emission centered at 580 nm, which is attributed to the incorporation of erbium ions into a silicon oxycarbide matrix. The obtained results indicate a direct correlation between the photoluminescence emission evolution and the presence of erbium oxide used during the deposition process. The observed photoluminescence emission is attributed to the formation of erbium-silica-based complexes that facilitate energy transfer to the erbium ions. This research opens new possibilities in areas such as optoelectronics, sensing, and telecommunications. The findings obtained have numerous potential applications, particularly in advancing the design of LEDs, lasers, and waveguides.
