Near-infrared persistent luminescence hollow mesoporous nanospheres have been synthesized via a template method. These nanospheres can be used as large capacity drug carriers and realize super long-term and high sensitivity tracking of drug delivery in deep tissue.
Transparent glass-ceramic is a highly attractive class of materials for photonic application. Transition metal ions are promising candidates for luminescence centers thanks to the sensitivity to the ligand ions of...
Y3(Al/Ga)5O12:Ce3+,Cr3+,Nd3+ nanocrystals with strong persistent luminescence in the NIR-II spectral region, which are highly desired for bioimaging, have been synthesized by a salt microemulsion method.
