TL;DR: An unusual electronic dual-bandgap structure, comprising the newly emerged semiconducting bandgap and original insulator bandgap of ≈3.96 eV, is found to be the underlying fundamental reason for the ultranarrow blue emission.

TL;DR: A unique strategy is reported for the synthesis of high-quality LiYbF4:Ln3+ core-only and core/shell UCNPs with tunable particle sizes and shell thicknesses and unraveled the dominant mechanisms of phonon-assisted cooperative energy transfer and sequential dimer ground- state absorption/excited-state absorption for the CSU process in LiYf4:Tb3+ UCNBP.

TL;DR: A simple and unique strategy to prepare a hydrophilic tumor-targeting photosensitizer ATF-ZnPc by covalently coupling zinc phthalocyanine to the amino-terminal fragment of urokinase-type plasminogen activator (uPA), a fragment responsible for uPA receptor (uPAR, a biomarker overexpressed in cancer cells), through the carboxyl groups of ATF is developed.

TL;DR: A sensitive, selective, and high-throughput bioassay for glucose in human serum and whole blood is achieved, thereby revealing the great potential of the UCNPs-PDA nanosystem for the accurate detection of blood glucose or other H2O2-generated biomolecules in clinical bioassays.

TL;DR: It was found that Nd3+ ions can be effectively sensitized by the ZnO nanocrystals, resulting in sharp and intense characteristic Nd 3+ luminescence.
