Ionic nanosphere as a novel sensitizer for luminescence from terbium(III) ion hybridized by facile ion-exchange process Open
Luminescence from terbium(III) species is typically weak due to its low absorption coefficient and slow radiative process despite its advantageous color purity. Hybridizing with a photosensitizer(s) is one of the most popular strategies to…

Impact of nanosizing a host matrix based on a metal–organic framework on solid-state fluorescence emission and energy transfer Open
We demonstrate that the nanosize effect of a host matrix appears to affect the emission properties of guest dye molecules encapsulated in the pores of a metal–organic framework as a host (dye@MOF).
