The use of zinc ions to control the size of Yb/Er:KMnF₃ nanocrystals with single band emission

CrystEngComm (2015)

Lei Lei Jiajia Zhou Junjie Zhang Shiqing Xu

A novel method to modify the size of Yb/Er:KMnF₃ NCs by introducing Zn²⁺ in the initial solution is presented, and the results can provide direct evidence for the size-dependent upconversion luminescence.

Trace Iron‐Modified CeO₂‐supported Core‐shell CoO@Co Catalyst for Selective Conversion of Furfural to 1,5‐Pentanediol

ChemSusChem (2024)

Shenyu Wang Junjie Zhang Ying Zhang

In the conversion of furfural using non-noble metal catalysts, preferential cleavage of the C2-O bond followed by hydrogenation of the C=C bond facilitates selective access to valuable 1,5-pentanediol (1,5-PeD). Herein, we developed CeO₂ loaded core-shell CoO@Co nanoparticle catalysts. Adjusting Co loading, Fe doping, and reduction temperature improved reaction efficiency. 7Co-0.2Fe/CeO₂ catalysts reduced at 500 °C demonstrated optimal performance. 1,5-PeD produced at 54.76 mmol/g

2.8 μm emission and OH quenching analysis in Ho3+ doped fluorotellurite-germanate glasses sensitized by Yb3+ and Er3+

Scientific Reports (2017)

Junjie Zhang Lu Yu Muzhi Cai Ying Tian Feifei Huang

The use of Yb3+ and Er3+ co-doping with Ho3+ to enhance and broaden the Ho3+: 5I6 → 5I7 ~2.8 μm emissions are investigated in the fluorotellurite-germanate glasses. An intense ~3 μm emission with a full width at half maximum (FWHM) of 245 nm is achieved in the Er3+/Ho3+/Yb3+ triply-doped fluorotellurite-germanate glass upon excitation at 980 nm. The glass not only possesses considerably low OH- absorption coefficient (0.189 cm-1), but also exhibits low phonon energy (704 cm-1). Moreover, the measured lifetime of Ho3+: 5I6 level is as high as 0.218 ms. In addition, the energy transfer rate to hydroxyl groups and quantum efficiency (η) of 5I6 level were calculated in detail by fitting the variations of lifetimes vs. the OH- concentrations. The formation ability and thermal stability of glasses have been improved by introducing GeO2 into fluorotellurite glasses. Results reveal that Er3+/Ho3+/Yb3+ triply-doped fluorotellurite-germanate glass is a potential kind of laser glass for efficient 3 μm laser.

Dual heterogeneous interfaces enhance X-ray excited persistent luminescence for low-dose 3D imaging

Nature Communications (2024)

Lei Lei Minghao Yi Yubin Wang Youjie Hua Junjie Zhang

Lanthanide-doped fluoride nanoparticles (NPs) showcase adjustable X-ray-excited persistent luminescence (XEPL), holding significant promise for applications in three-dimensional (3D) imaging through the creation of flexible X-ray detectors. However, a dangerous high X-ray irradiation dose rate and complicated heating procedure are required to generate efficient XEPL for high-resolution 3D imaging, which is attributed to a lack of strategies to significantly enhance the XEPL intensity. Here we report that the XEPL intensity of a series of lanthanide activators (Dy, Pr, Er, Tm, Gd, Tb) is greatly improved by constructing dual heterogeneous interfaces in a double-shell nanostructure. Mechanistic studies indicate that the employed core@shell@shell structure could not only passivate the surface quenchers to lower the non-radiative relaxation possibility, but also reduce the interfacial Frenkel defect formation energy leading to increase the trap concentration. By employing a NPs containing flexible film as the scintillation screen, the inside 3D electrical structure of a watch was clearly achieved based on the delayed XEPL imaging and 3D reconstruction procedure. We foresee that these findings will promote the development of advanced X-ray activated persistent fluoride NPs and offer opportunities for safer and more efficient X-ray imaging techniques in a number of scientific and practical areas.

Surface Micron-Structure Engineering of Halide Perovskite Doped Glass-Ceramic and Its Ionic Transport Application

ACS Applied Energy Materials (2021)

Wenqing Xie Jianghang Cao Feifei Huang Meiqiang Fan Jincheng Du

Halide perovskite crystals embedded in oxide glass matrix have inspired recent researches, owing to their applications in photoelectrical devices, but the dimension-tunable structures have rarely applied in electrochemical property enhancement. Herein, a novel glass-ceramic with mixed 0D/3D perovskite quantum dots (PQDs) as an anode material was fabricated by a traditional melt-and-quench method, and the growth patterns in the bulk or on the surface of the glass were systematically studied.Two types of microstrutures with dendrite and flake type of morphologies were devloped. The encapsulated micron-sized derivatives show outstanding ionic transport property as a potential anode material for Li-ion batteries (LiBs), manifesting long cyclic life, high specific capacity retention and increased rate performance. Additionally, the glass matrix serves as a media to accomodate lattice expansion of crystals, avoiding structure collapse and stabilizing ion transport channels. The verifiable lithiation mechanism and practical properties open the door for electrochemical applications of halide perovskite containing glass-ceramic materials.
