Single upconverting nanoparticle UC-FRET studies

13 styczeń 2024

Use of upconverting nanoparticles (UCNPs) as donors comes with some complications. Donor ions are characterized by their long lifetimes (hundreds of microseconds) and outnumber the acceptor dye molecules. On the contrary, the lifetimes of organic ...

Photon Avalanche emission

13 styczeń 2024

Among different anti-Stokes emissions, where emitted photons have larger energy than the absorbed photons, photon avalanche (PA) phenomenon is unique. It originates from a very non-linear increase of luminescence intensity in response to minu...

Light-to-heat conversion

Agnieszka Paściak (LuNASI, within NanoTBTech project) has prepared a video presentation about how we measure light-to-heat conversion efficiency. This is related to the patent application "Measurement system and a method for determining ...

LuNASI - Luminescent Nanoparticles for Sensing and Imaging

Lanthanide doped luminescent nanoparticles (LnNPs) show promise as alternative luminescent organic labels (dyes, fluorescent proteins, gold nanoparticles or nanorods, carbon nanodots, quantum dots etc).

Förster Resonance Energy Transfer

Förster Resonant Energy transfer (FRET) is a generic method to study interaction between two fluorescent maieties - the donor (D) and the acceptor (A). Energy absorbed by the donor may be transfered non-raidatively to the acceptor under two c...

Luminescent thermometry

Phosphor Assisted Temperature Sensing and Imaging Temperature distribution (raster scanned mapping or imaging) is typically performed by either cooled narrow-band-gap semiconductor (i.e., InAt, InAs, HgCdTe, PbS, PbSe) or microbolometric (i.e., a...
