TL;DR: By rational design of a core-shell structure with a set of lanthanide ions incorporated into separated layers at precisely defined concentrations, efficient upconversion emission can be realized through gadolinium sublattice-mediated energy migration for a wide range of Lanthanide activators without long-lived intermediary energy states.

TL;DR: Recent developments in optical biolabeling and bio-imaging involving upconversion nanoparticles are reviewed, simultaneously bringing to the forefront the desirable characteristics, strengths and weaknesses of these luminescent nanomaterials.

TL;DR: These findings show great promise of K2TiF6:Mn(4+) as a commercial red phosphor in warm white LEDs, and open up new avenues for the exploration of novel non-rare-earth red emitting phosphors.

TL;DR: A comprehensive survey of the latest advances made in developing lanthanide-doped inorganic nanoparticles as potential luminescent bioprobes covering areas from their fundamental chemical and physical features to bioapplications including controlled synthesis methodology, surface modification chemistry, optical spectroscopy, and their promising applications in diverse fields are provided.

TL;DR: This review focuses on the most recent advances in the development of lanthanide-doped UCNPs as potential luminescent nano-bioprobes by means of the authors' customized lanthanides photophysics measurement platforms specially designed for upconversion luminescence.
