1. 1. Dye sensitzation effects on lanthanide upconversion nanoparticles

   University essay from KTH/Fysik

   Author : Dag Albin Bäck; Andreas Jörgensen; [2022]
   Keywords : Dye sensitization; lanthanide upconversion nanoparticles; upconversion nanoparticles; UCNP; IR806;

   Abstract : In this report we studied the properties of the dye IR806 and possible mechanisms of the dye sensitization effect on ytterbium-erbium co-doped upconversion nanoparticles. We found that the dye IR806 has two primary emission peaks in the NIR spectral range at around 850 nm and at around 950 nm. READ MORE

   Abstract : The name Upconverting nanoparticles refers to a novel category of luminescence emitters that are capable of generating visible luminescence upon excitation with noncoherent and longer wavelength monochromatic near-infrared light, at excitation fluence rates as low as 1-103 W/cm2. This unique optical behaviour is of great interest to researchers as it could potentially allow for virtually autofluorescence free luminescence imaging of living tissue. READ MORE
