Article Abstract
SiO@GdPO:Tb@SiO nanoparticles with core-shell-shell structure were successfully synthesized by a cheap silane coupling agent grafting method at room temperature. This method not only homogeneously coated rare-earth phosphate nanoparticles on the surface of silica spheres but also saved the use of rare-earth resources. The obtained nanoparticles consisted of SiO core with a diameter of approximately 210 nm, GdPO:Tb intermediate shell with thickness of approximately 7 nm, and SiO outer shell with thickness of approximately 20 nm. This unique core-shell-shell structured nanoparticles exhibited strong luminescence properties compared with GdPO:Tb nanoparticles. The core-shell-shell structured nanoparticles can effectively quench the intrinsic fluorescence of bovine serum albumin through a static quenching mode. The as-synthesized nanoparticles show great potential in biological cell imaging and cancer treatment.

Lanthanide-doped fluoride nanoparticles show great potential for optical thermometry and bioimaging. However, their applications are still constrained by inherent limitations in luminescence intensity and functional versatility. To overcome these challenges, we propose a core-active shell-inert shell nanostructure that integrates multifunctional capabilities within a single platform.

Phosphorus contamination in water systems poses a significant environmental threat, necessitating the need for effective phosphate removal methods. A novel magnetic composite, magnetic FeO@MIL-100(Fe)@Mg-Al layered double hydroxide (LDH), synthesized through a solid-state transformation of MIL-100(Fe) from FeO followed by in-situ growth of Mg-Al LDH. This innovative hierarchical core/shell/shell structure leverages the magnetic properties of FeO for easy separation, utilizes MIL-100(Fe) to grow and orient the LDH, and exploits the large ion exchange capacity of Mg-Al LDH nanosheets for efficient phosphate capture.

Lanthanide-doped upconversion nanoparticles are promising for applications ranging from biosensing, bioimaging to solid-state lasing. However, their brightness remains limited by the concentration quenching effect of lanthanide activator ions, which greatly restricts their utility. Here, we develop a heterogeneous core-shell-shell nanostructure based on hexagonal NaYF, in which Tm activator and Yb sensitizer are separated into the core and inner shell, while the outmost shell is used to suppress surface quenching effects.

Lanthanide (Ln)-enriched upconversion nanoparticles (UCNPs) with high dopant concentrations have garnered significant attention due to their unique optical properties. However, their practical applications are hindered by the deleterious concentration quenching effect. Herein, through kinetic modeling of Er excited-state dynamics employing energy diffusion theories, we demonstrate that concentration quenching in LiErF UCNPs predominantly originates from long-range energy migration through the I level toward surface and lattice defects, rather than the conventionally attributed cross-relaxation mechanism.

Core/shell nanostructures of type I and type II band-offset materials have been pivotal in improving photoluminescence and imparting charge separation in well-established colloidal quantum dots. In addition to these features, the multishell motif provides a simple means to expand the emission spectral range and spatially fine-tune electron and hole wave functions. Here, we explore the CdSe/CdTe/CdSe core/shell/shell structure with a total diameter of ≲7 nm, within the practical limits of readily accessible synthesis capabilities.
