    distribution. Upon ultraviolet (UV) excitation, LaPO4:Ce/Tb and LaPO4:Ce/Tb@Au MMs exhibit the characteristic green emissions of Tb3+ ions. In addition, the good biocompatibility and sustained doxorubicin (DOX) release properties indicate its promise as a candidate in cancer therapy. In particular, under UV irradiation, a rapid DOX release was achieved due to the photothermal effect of Au NPs derived from the
    均一的LaPO 4:Ce / Tb介孔微球(MMs )已通过温和的反应条件下的简便大规模生产共沉淀工艺成功制备,无需使用任何表面活性剂,催化剂或进一步热处理。然后,金纳米粒子(NPs)通过静电相互作用与聚醚酰亚胺(PEI)修饰的LaPO 4:Ce / Tb MMs共轭。发现制备的LaPO 4:Ce / Tb @ Au复合材料由具有高表面积和窄孔径分布的良好分散的介孔微球组成。在紫外线(UV)激发下,LaPO 4:Ce / Tb和LaPO 4:Ce / Tb @ Au MM表现出Tb 3+的特征性绿色发射离子。此外,良好的生物相容性和持续的阿霉素(DOX)释放特性表明其有望成为癌症治疗的候选药物。特别地,在紫外线辐射下,由于金纳米粒子的Tb 3+的绿色发射和金纳米粒子的表面等离振子共振(SPR)带在约530 nm的重叠而产生的金纳米粒子的光热效应,实现了DOX的快速释放。MTT分析,细胞摄取

    Multicolor and monodisperse La2O3:Ln3+ (Ln3+ = Eu3+, Tb3+, Dy3+, Sm3+, Er3+, Ho3+, Tm3+, Yb3+/Er3+, Yb3+/Ho3+) microspheres were prepared by a homogeneous precipitation method followed by a subsequent calcination process. X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared (FT-IR), thermogravimetric and differential thermal analysis (TG-DTA), and photoluminescence (PL) spectra were employed to characterize the samples. The results indicate that the La2O3 microspheres can be well indexed to the hexagonal La2O3 phase. In addition, the possible formation mechanism and the chemical reaction of each step to form spherical La2O3 microspheres are proposed according to the concerned analysis. The as-obtained particles show strong light emission with different colors corresponding to different Ln3+ ions under ultraviolet-visible light excitation. Under 980 nm NIR irradiation, the Lu2O3:Ln3+ (Ln3+ = Yb3+/Er3+, and Yb3+/Ho3+) microspheres exhibit characteristic up-conversion emissions of red (Er3+, 2H11/2, 4S3/2, 2H11/2 → 4I15/2), and green (Ho3+, 5F4, 5S2, 5F5 → 5I8), respectively. These merits of multicolor emissions in the visible region endow this kind of material with potential applications in the field of light display systems, lasers, and optoelectronic devices.

    水性条件下的水热还原被广泛用于将生物质转化为更有价值的产品。但是,该方法固有的苛刻条件会不可逆地改变载体的固有结构,以及将金属离子溶解到水溶液中。在这项工作中,我们首次合成了一种新的高度水热稳定的Ru / LaCO 3 OH催化剂,该催化剂主要由被LaCO 3 OH载体部分包封的Ru纳米颗粒组成,具有强大的金属-载体相互作用(SMSI),具有很高的稳定性。生物质模型分子愈创木酚和甘油的氢解中,在水热还原条件下对催化剂的活性和活性。浸渍过程中,RuCl 3 ·3H 2O前体首先与LaCO 3 OH反应形成LaRu(CO 3)2 Cl 2络合物和LaOCl。XPS证明Ru以氧化态存在,TEM和XRD显示不存在Ru 0,而XRD图谱显示存在LaOCl的特征晶格条纹。尽管LaRu(CO 3)2 Cl 2配合物在350°C时能抵抗H 2还原,但在240°C的水热条件下,该配合物容易还原为Ru 0。在随后的过程中,LaRu(CO

    Europium and terbium-doped lanthanum hydroxycarbonate and lanthanum oxycarbonate nanoparticles were fabricated under two different reaction conditions using lanthanide acetate and urea as the starting materials. The photoluminescence properties of these hydroxycarbonate and oxycarbonate particles, and of their colloidal suspensions in water, were studied. The Eu3+ 5D0→7FJ and Tb3+ 5D4→7FJ emission spectra and the luminescence lifetimes in the two carbonate matrices were measured. Terbium-doped cerium oxycarbonate particles were synthesized, and the energy transfer process from Ce3+ to Tb3+ was investigated. The synthesis of lanthanum and cerium oxycarbonates was also carried out in the presence of stabilizing ligands: glucose and fructose. The influence of these ligands on the structure and luminescence was explored.
