Non-invasive precise thermometers working at the nanoscale with high spatial resolution, where the conventional methods are ineffective, have emerged over the last couple of years as a very active field of research. This has been strongly stimulated by the numerous challenging requests arising from nanotechnology and biomedicine. This critical review offers a general overview of recent examples...

A solution to develop high-brightness incoherent sources consists in luminescent concentration. Indeed, the absorption/emission process a high index medium allows us circumvent brightness conservation law by confinement of light 1 or 2 dimensions. In practice, Ce-doped concentrators pumped with InGaN LED exceed LED’s one order magnitude. This work shows how 3 dimensions increases an additional ...

We report luminescent characteristics and mechanical stability of a flexible organic light-emitting diode (FOLED) using an amorphous ZnO-doped In2O3 (a-IZO) anode with a low sheet resistance of and a high optical transparency of 86%. The FOLED consisting of a-IZO/poly(3,4-ethylenedioxythiophene) poly(styrenesulfonate) (PEDOT:PSS)/poly[(9,9-di-n-octylfluorenyl-2,7-diyl)-alt-(benzo[2,1,3]thiadiaz...

Diamond is valuable material with extraordinary high thermal conductivity and transparency in a wide spectral range from UV to IR longer wavelengths. Defects impurities the diamond lattice can absorb emit light at wavelengths specific for each of such “color centers.” Particularly, vacancy-related defects diamond, as nitrogen-vacancy (NV) or silicon-vacancy (SiV) centers, are actively investiga...
