“…3, in the low frequency region, the band at 641 cm −1 was attributed to the stretching vibration of Ga/La-O. 23 The bands at 483 cm −1 and 520 cm −1 belonged to the stretching energy band, which was caused by the Ge-O and Si-O bond, respectively. 24 The band at 768 cm −1 and 901 cm −1 can be ascribed to the La-O stretching vibrations.…”

“…[1,2] And further in the practical research and application of the rare earth functional material, the trace level doped REEs with slightly different chemical compositions will lead to changes in the properties, which can be mainly attributed to the particularity of the electronic configuration of REEs. [1,3] In order to accurately determine the chemical composition of trace REEs in materials under laboratory conditions, it is necessary to adopt advanced analytical techniques like the methodology of x-ray fluorescence (XRF), which is crucial for gaining insight into more potential applications of REOs. [4][5][6] In XRF, the electron within the sample atom is excited when irradiated by a primary x-ray beam.…”

“…In particular, for XRF research and analyses involving REEs, L-edge emission lines of high-Z REEs are preferred over the more intense K-edge emission lines, which necessitate excitation energies beyond the capabilities of most laboratory-based x-ray sources, despite constraints caused by adjacent emission line overlap. [3,13] In addition, due to the limitation of the spectrometer resolution, the measured emission spectra of REEs may also overlap with the K-edge emission lines of 3d transition metals, such as Fe, Co, Ni, etc., which are usually with much higher abundance in natural materials. [14] The energy resolution required for those measurements has exceeded the capabilities provided by traditional elemental analysis instruments or spectroscopies, with the energy dispersive spectrometer (EDS) as one of the representatives.…”

The accurate analysis of the elemental composition plays a crucial role for the research of functional materials. The emitting characteristic X-ray Fluorescence (XRF) photons can be used for precisely discriminating the specified element. The detection accuracy of conventional XRF methodology using semiconductor detector is limited by the energy resolution, thus poses a challenge on accurately scaling the actual energy of each XRF photon. We adopt a novel high-resolution X-ray spectrometer based on the superconducting Transition-edge Sensor (TES) for the XRF spectroscopy measurement of different elements. Properties including high energy resolution, high detection efficiency and precise linearity of the new spectrometer will bring significant benefits in analyzing elemental composition via XRF. In this paper, we study the L-edge emission line profiles of three adjacent rare earth elements with the evenly mixed sample of their oxide components: Terbium, Dysprosium and Holmium. Two orders of magnitude better energy resolution is obtained compared to a commercial silicon drift detector. With this TES-based spectrometer, the spectral lines overlapped or interfered by background can be clearly distinguished, thus making the chemical component analysis more accurate and quantitative. A database of coefficient values for line strength of the spectrum can then be constructed thereafter. Equipped with the novel XRF spectrometer and an established coefficient database, a direct analysis of the composition proportion of a certain element in an unknown sample can be achieved with high accuracy.

“…The pump photon energy of 980 nm can be efficiently absorbed by Yb 3þ and then transferred to the neighboring Tm 3þ to achieve its efficient 1.8 μm mid-infrared luminescence. [13][14][15] However, this pump scheme is only available for the 980 nm excitation wavelength and is useless for other infrared-excitation wavelengths. Recent work showed that Er 3þ is also a good sensitizer apart from Yb 3þ .…”

Mid‐infrared luminescence at around 1.8 μm has shown great potential in many frontier photonic fields. However, how to realize the 1.8 μm emission of Tm3+ with multiple pump wavelengths and in particular in nanosized hosts has remained a challenge so far. Herein, an erbium sublattice–based core–shell nanostructure is proposed to achieve the multiwavelength excitable mid‐infrared emission of Tm3+ at around 1.8 μm from its 3F4 → 3H6 transition. The core–shell engineering and cross‐relaxation help to improve the population of Er3+ at its 4I13/2 energy level and subsequent energy transfer to Tm3+ (3F4) for its efficient 1.8 μm emission upon 808, 980, and 1530 nm excitations. The modulation of energy‐transfer channels by codoping other rare‐earth ions shows that introducing a small amount of Ce3+ into the erbium sublattice can enhance the 1.8 μm emission of Tm3+ through favorable cross‐relaxation processes. Moreover, the 1.8 μm emission is further significantly enhanced by designing a core–shell–shell nanostructure with a NaYF4:Yb‐sensitizing interlayer, which is able to maximize the absorption of 980 nm excitation energy. These results provide a new conceptual nanosized model for mid‐infrared luminescent materials toward infrared biophotonics and microlasers.
