“…In above measurements, when the EFTL is l , the thickness of the sample is T , the height of the slit is D , then the emission intensity I ( l ) at a certain wavelength can be presented as

I false(l false) = \frac{I_{s} T D}{g} false[exp (g l) - 1 false]

where g is NOGC at the certain wavelength, and I s is the excitation intensity per unit volume. To obtain the g values and investigate the influence of emission wavelength on it, the dependences of emission intensities at different wavelengths on the EFTL extracted from Figure A were displayed in Figure B.…”

“…In above section, we evaluated the optical amplification ability of the borate glass containing silver aggregates. Besides the optical gain, the thermal stability of spectral property is also one of the important factors which affect the laser operation performance since the laser media may work at high temperature induced by heat deposition of the pump light . In this section, we examined the temperature dependence of luminescence property in the studied glass.…”

Spectroscopic properties of Sm3+‐doped borate glass with silver aggregates were investigated, and it was found that the glass presented broad excitation and emission band covering violet‐infrared region. Furthermore, the optical gain coefficients at various wavelengths were measured via an amplified spontaneous emission technique, it was confirmed that the glass displayed flat net optical gain coefficient in almost full visible region. In addition, the fluorescent temperature quenching of the glass was examined, and it was seen that about 50% of room temperature emission intensity was kept when the sample was heated up to 325°C.

“…Phase transfer hydrothermal synthesis is an emerging synthetic method for the preparation of inorganic materials based on traditional hydrothermal synthesis. The entire reaction process requires high temperature and closed reaction vessel conditions [ 72 , 73 ], and the solution show a variety of excellent advantages for preparing lanthanide-based UCNPs at room temperature, such as increased of solubility and ion activity [ 74 , 75 ]. Li et al provided a detailed description of such carboxylic acids and inorganic metals transfer phase alkylation reaction system based on the thermal brine synthesis mechanism (Fig.…”

Multifunctional lanthanide-based upconversion nanoparticles (UCNPs), which feature efficiently convert low-energy photons into high-energy photons, have attracted considerable attention in the domain of materials science and biomedical applications. Due to their unique photophysical properties, including light-emitting stability, excellent upconversion luminescence efficiency, low autofluorescence, and high detection sensitivity, and high penetration depth in samples, UCNPs have been widely applied in biomedical applications, such as biosensing, imaging and theranostics. In this review, we briefly introduced the major components of UCNPs and the luminescence mechanism. Then, we compared several common design synthesis strategies and presented their advantages and disadvantages. Several examples of the functionalization of UCNPs were given. Next, we detailed their biological applications in bioimaging and disease treatment, particularly drug delivery and photodynamic therapy, including antibacterial photodynamic therapy. Finally, the future practical applications in materials science and biomedical fields, as well as the remaining challenges to UCNPs application, were described. This review provides useful practical information and insights for the research on and application of UCNPs in the field of cancer.

Photoluminescence spectra are investigated in erbium-doped GaLaS(O) glasses. Under optical pumping by a semiconductor laser diode operating at 808 nm, the samples demonstrate intense "green" emission bands centered at around 525 and 550 nm as well as much weaker "red" emission band centered at around 664 nm. The intensities of "green" and "red" emission bands are investigated as a function of pumping intensity. The cascade mechanism of generation of radiation from higher lying levels of the 4f-shell Er 3þ ions is discussed to interpret these experimental results and the theoretical description of the phenomenon is developed.
