“…This value is close to the highest reported η iQE of Tb 3+ -based PL in literature, e.g. , Tb 3+ -doped phosphate glass (~78%)40 and silicone hybrid materials (~68%)41. For higher doping concentration, it decreases to only 0.3% at x = 25.…”

The σ em value of Tb 3+ in GBAG- x Tb glasses at 542 nm is ~1.1 × 10 −21 cm 2 , notably larger than in phosphate glasses (~7.4 × 10 −22 cm 2 )40. The product of σ em * τ , the optical gain parameter for laser applications, is proportional to the amplification gain and inverse laser oscillation threshold45.…”

We report on the magneto-optical (MO) properties of heavily Tb3+-doped GeO2-B2O3-Al2O3-Ga2O3 glasses towards fiber-integrated paramagnetic MO devices. For a Tb3+ ion concentration of up to 9.7 × 1021 cm−3, the reported glass exhibits an absolute negative Faraday rotation of ~120 rad/T/m at 632.8 nm. The optimum spectral ratio between Verdet constant and light transmittance over the spectral window of 400–1500 nm is found for a Tb3+ concentration of ~6.5 × 1021 cm−3. For this glass, the crystallization stability, expressed as the difference between glass transition temperature and onset temperature of melt crystallization exceeds 100 K, which is a prerequisite for fiber drawing. In addition, a high activation energy of crystallization is achieved at this composition. Optical absorption occurs in the NUV and blue spectral region, accompanied by Tb3+ photoluminescence. In the heavily doped materials, a UV/blue-to-green photo-conversion gain of ~43% is achieved. The lifetime of photoluminescence is ~2.2 ms at a stimulated emission cross-section σem of ~1.1 × 10−21 cm2 for ~ 5.0 × 1021 cm−3 Tb3+. This results in an optical gain parameter σem*τ of ~2.5 × 10−24 cm2s, what could be of interest for implementation of a Tb3+ fiber laser.

“…Terbium (Tb 3+ ) doped glasses and glass ceramics exhibit week blue and intense green emissions useful in multicolor emitting LEDs, plasma display panels and display devices etc. Tb 3+ doped glass fibers find handy in non-destructive testing and medical applications as high resolution medical X-ray imaging fields such as mammography and also used to reduce the radiative dose when exposed to patients [10,11]. With regard to Samarium, it exist in Sm 3+ and Sm 2+ states depending on the irradiation source and site/environment of the host matrix into which it is incorporated.…”

“…Phosphate glasses are characterized by unique properties, which are: high transmission in the range of UV-VIS-NIR, low refractive index (n = 1.5), dispersion, thermal stability, mechanical resistance and the ability to adopt high concentration of RE ions [4,5]. It is high solubility of rare earth ions in multicomponent phosphate glasses that enables the construction of fiber amplifiers and fiber lasers [6][7][8]. On the other hand, the absorption edge in the range of short wavelengths of 200 nm enables to use them as active materials for the detection of UV radiation [9].…”

In the article analysis of UV absorption and visible fluorescence of Sm 3+ and Tb 3+ ions doped phosphate glass with molar composition: 65P 2 O 5 + 8Al 2 O 3 + 10BaO + 17(Na 2 O + MgO + ZnO) have been investigated. As a result of optical pumping fabricated glass with radiation from a deuterium lamp four luminescence bands were observed near to the wavelength of 600 nm for Sm 3+ ions and 550 nm for Tb 3+ ions. It was found that larger energy gap between laser and ground levels leads to the strongest emission in the visible range in terbium doped glasses than in glasses doped with samarium ions. Both fabricated glasses are characterized by the ability to selectively detect the radiation in the UV range.
