Luminescence characteristics of Sr2B5O9Cl: Eu2+ phosphors for white LED

Acta Physica Sinica (2010)

Ding Xu Xu Yan Chongfeng Guo

A series of blue-emitting phosphors M2B5O9Cl: Eu2+(M=Ca, Sr) were synthesized by solid-state methods. And the phosphors were characterized by XRD and photoluminescence emission (PL) and excitation (PLE) spectra. The factors that affect the PL intensity of phosphor Sr2B5O9Cl have been investigated, and the optimal conditions to obtain the blue emitting phosphor are 8 mol% Eu2+concentration, 5.0mol % excess of SrCl2. As Ca partially or completely substituted Sr in the host Sr2B5O9Cl, the emission peak shifts from 425 to 453 nm. The most important is that the phosphors M2B5O9Cl: Eu2+(M=Ca, Sr) show strong absorption in the region of 350—400 nm, which matches well with the emission of the near-ultraviolet or purple LED chips. Comparison with the commercial blue-emitting phosphor, the PL intensity of phosphor Sr1.92Eu0.08B5O9Cl is about 1.8 times that of the commercial blue emitting phosphor BAM. Thus, the phosphors M2B5O9Cl: Eu2+ (M=Ca, Sr) show great potential as the candidate for blue phosphor in n-UV or purple based white LEDs.

Synthesis, Structure and Magnetic Property of a Two-dimensionalStair-like Framework: [Ni(μ_(1,5)-dca)_2(en)]_n

Wuji huaxue xuebao (2004)

Xu Yan

A new nickel(II)-dicyanamide compound, [Ni(dca)2(en)]n (1) (dca=dicyanamide anion, -); en=ethylene diamine), has been synthesized and its structure has been determined by single crystal X-ray diffraction analysis. The crystal is monoclinic, space group P21/n with unit cell dimensions: a=0.694 3(1) nm, b=1.041 5(2) nm, c=1.413 2(2) nm, and β=90.381°, Z=4, V=1.011 0(3) nm3. In this compound, the adjacent nickel atoms are connected by dca all inμ1,5-bridging mode to form ladder-like units, which are linked with double dca bridges to generate a regular infinite stair-like structure. Temperature-dependent magnetic susceptibility was also characterized for this compound. CCDC: 208276.

Characterization and preparation of food-derived peptides on improving osteoporosis: A review

Food Chemistry X (2024)

Zhe Xu Rui Zhang Hongrui Chen Lijuan Zhang Xu Yan

Osteoporosis is a systemic bone disease characterized by reduced bone mass and deterioration of the microstructure of bone tissue, leading to an increased risk of fragility fractures and affecting human health worldwide. Food-derived peptides are widely used in functional foods due to their low toxicity, ease of digestion and absorption, and potential to improve osteoporosis. This review summarized and discussed methods of diagnosing osteoporosis, treatment approaches, specific peptides as alternatives to conventional drugs, and the laboratory preparation and identification methods of peptides. It was found that peptides interacting with RGD (arginine-glycine-aspartic acid)-binding active sites in integrin could alleviate osteoporosis, analyzed the interaction sites between these osteogenic peptides and integrin, and further discussed their effects on improving osteoporosis. These may provide new insights for rapid screening of osteogenic peptides, and provide a theoretical basis for their application in bone materials and functional foods.
