Upconverting Gd2O3 nanoparticles (NPs) doped 1% Er3+ and 18% Yb3+ permits one to perform optical imaging. Because of the presence of Gd3+ they are useful in MRI. The main challenge is to enhance the NPs upconversion efficiency. As a result of co-dopi

Nanostructures as color-tunable luminescent markers have become major, promising tools for bioimaging and biosensing. In this paper separated molybdate/Gd2O3 doped rare earth ions (erbium, Er3+ and ytterbium, Yb3+) core–shell nanoparticles (NPs), w

We study the fluorescence properties of peridinin-chlorophyll-protein light-harvesting complex reconstituted with both chlorophyll a and chlorophyll b coupled to spherical gold nanoparticles. Since there is a bidirectional energy transfer between the

We describe the optical properties of a simple plasmonic network, which consists of silver nanowires coupled with nanocrystals doped with rare-earth-ions. The nanocrystals exhibit anti-Stokes emission called up-conversion. First of all, we demonstrat

We studied physical properties of hybrid nanostructures consisting of α-NaYF4:Tm3+/Yb3+ nanocrystals coupled to single silver nanowires. By using confocal fluorescence microscope we observed much higher intensity of the upconversion emission form na

In this paper we demonstrate direct excitation of propagating plasmons in silver nanowires. The plasmons are excited either directly by an infrared excitation or indirectly via up-conversion process in rare-earth doped nanocrystals placed in the vici

Natural capacity has evolved in higher plants to absorb and harness excessive light energy. In basic models, the majority of absorbed photon energy is radiated back as fluorescence and heat. For years the proton sensor protein PsbS was considered to
