Presented review is devoted only to luminescent thermometers at nanoscale and gives the classification of all luminescent thermometers depending on the type of temperature dependent spectroscopic feature like intensity, band shape, intensity, bandwidth, band shape, polarization, spectral shift and lifetime. In this paper readers may find characterization of wide range different type of non contact temperature sensors based on quantum dots, rare earth doped systems, thermometers based on polymers, dyes, and luminescent nano-gels. The great importance of this temperature sensing technique associated among others with their high spatial resolution is confirmed by impressive number of their application in living cells, microfluidics, electronic nano-devices and solid state lasers. A great emphasis has been placed on the considering of possibility of applying luminescent thermometers in biomedical field. Up to date (2012) great number of luminescent thermometers worked in visible spectral region therefore authors suggest that the main effort should be put on the development of the new type of luminescent thermometers working (for which both absorption and emission bands) are localized in optical window of biological tissue (near infrared spectral region, NIR) . During next few years after publishing this paper, according to this suggestion, new class of NIR-absorbing NIR-emitting luminescent thermometers has been developed, but this is a story for the next few posts…
