Abstract

In this paper we report two different doping strategies to prepare a series of novel HAp:Ln3+ (Ln = Eu or Tb) nanocrystals with tunable aspect ratios via facile hydrothermal synthetic routes. Adopting a one-pot synthetic strategy, with increasing rare-earth doping dosage, the as-prepared nanocrystals have relatively weak fluorescence intensity, and change from nanorods with lengths of about 150 nm into nanowires with lengths of about 2 μm. Using the synthetic pure HAp nanorods as matrices, they are endowed with bright green or red luminescent properties by doping Tb3+ or Eu3+ ions via a second hydrothermal process, and simultaneously retain their original morphologies (diameter 8 nm, length 150 nm). The hydrophobic HAp:Ln3+ nanorods with strong optical properties are converted into hydrophilic particles with a surfactant (Pluronic F127) and successfully applied to live cell imaging.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
