Abstract

We report for the first time a self-produced bubble-template synthesis of La2O3:Yb/Er hollow mesoporous spheres (HMSs) through a facile one-step co-precipitation process. The temperature, which determines bubble formation, and the amounts of citric acid and NaOH, which determine dispersibility, are the main factors in the formation of La2O3:Yb/Er HMSs. Au nanocrystals (NCs) with a particle size of 9 nm were conjugated to the as-prepared HMSs without adding any organic reagents. It is noted that the up-conversion (UC) luminescence intensity of La2O3:Yb/Er@Au was markedly improved by 49.7-fold under low pump power, and the lifetime has been greatly enhanced due to the local field enhancement (LFE) of Au NCs, which effectively prevents the energy transfer from La2O3:Yb/Er to Au nanoparticles (NPs). The enhanced properties have been successfully proved by discrete-dipole approximation (DDA) simulation. The as-prepared La2O3:Yb/Er@Au HMSs with large surface area (118 m2 g−1) and mesoporous feature (2.92 nm in pore size) exhibit good compatibility. In addition, doxorubicin (DOX) release properties and obvious cytotoxicity to MCF-7 tumor cells reveal their potential application as a drug carrier. In particular, the facile and mass-production synthetic strategy may pave the way for the production of a wide class of materials.

Using Techniques and methods including… Single crystal and powder X-ray, electron, and neutron diffraction, solid-state spectroscopy, spectrometry, and microscopy, modelling and data mining, and empirical, semi-empirical and ab-initio theoretical evaluations. On crystalline and solid-state materials. We particularly welcome work on MOFs, coordination polymers, nanocrystals, host-guest and multi-component molecular materials. We also accept work on peptides and liquid crystals. All papers should involve the use or development of a design or optimisation strategy. Routine structural reports or crystal morphology descriptions, even when combined with an analysis of properties or potential applications, are generally considered to be outside the scope of the journal and are unlikely to be accepted.
