Following astonishing growth in the last decade, field of luminescence thermometry has reached stage becoming a mature technology. To achieve that goal, further developments should resolve inherent problems and methodological faults to facilitate its widespread use. This perspective presents recent findings thermometry, with aim providing guide for reader paths which this is currently directed. Besides well-known temperature read-out techniques, are outlined compared terms performance, some...
Nonaqueous reactions between titanium(IV) chloride and alcohols (benzyl alcohol or n-butanol) were used for the synthesis of anatase TiO2 particles, while rutile particles synthesized in aqueous media by acidic hydrolysis chloride. The X-ray diffraction measurements proved exclusive presence either phase prepared samples. photoluminescence both kinds (anatase rutile) with several well-resolved peaks extending visible spectral region was observed, quantum yield at room temperature found to be...
Synthesis of Eu(3+)- and Er(3+)/Yb(3+)-doped GdVO4 nanoparticles in reverse micelles their multifunctional luminescence properties are presented. Using cyclohexane, Triton X-100, n-pentanol as the oil, surfactant, co-surfactant, respectively, crystalline with ~4 nm diameter prepared at low temperatures. The particle size assessed using transmission electron microscopy is similar to crystallite obtained from X-ray diffraction measurements, suggesting that each comprises a single crystallite....
The mechanisms underlying the cytotoxic action of pure fullerene suspension (nano-C60) and water-soluble polyhydroxylated [C60(OH)n] were investigated. Crystal violet assay for cell viability demonstrated that nano-C60 was at least three orders magnitude more toxic than C60(OH)n to mouse L929 fibrosarcoma, rat C6 glioma, U251 human glioma lines. Flow cytometry analysis cells stained with propidium iodide (PI), PI/annexin V-fluorescein isothiocyanate, or redox-sensitive dye dihydrorhodamine...
This study explores potential of Er3+-Yb3+ doped phosphors for up-conversion luminescence thermometry in the temperature range from 10 K to 300 K. Yttrium oxide nanopowder with trivalent ytterbium and erbium ions (Y1.97Yb0.02Er0.01O3) was prepared by hydrothermal synthesis as an example. The intensity ratios emissions thermally coupled 2H11/2 4S3/2 levels Er3+ show strong dependence (in 150 K–300 K) much higher relative sensitivity than those reported above room based materials. maximal...
Lanthanide-doped vanadate thin films offer (i) a promising platform for luminescence-based noncontact temperature sensing; (ii) ratiometric/self-referencing absolute measurements; (iii) exceptional repeatability and reversibility multirun uses long life cycle; (iv) 2% K−1 maximum sensitivity (among the highest recorded inorganic nanothermometers); (v) resolution greater than 0.5 K; (vi) potential high-resolution 2D mapping. As service to our authors readers, this journal provides supporting...

Over same range, readout lifetime offers...
The spectroscopic properties of different infrared-emitting neodymium-doped nanoparticles (LaF3:Nd3+, SrF2:Nd3+, NaGdF4: Nd3+, NaYF4: KYF4: GdVO4: and Nd:YAG) have been systematically analyzed. A comparison the spectral shapes both emission absorption spectra is presented, from which relevant role played by host matrix evidenced. lack a “universal” optimum system for infrared bioimaging discussed, as specific application experimental setup imaging determine nanoparticle to be preferentially...
Ratiometric luminescence thermometry employing within the biological transparency windows provides high potential for biothermal imaging. Nd3+ is a promising candidate that purpose due to its intense radiative transitions (BWs) I and II simultaneous efficient excitability BW I. This makes almost unique among all lanthanides. Typically, emission from two 4F3/2 crystal field levels used but small ~100 cm−1 energy separation limits sensitivity. A higher sensitivity physiological temperatures...
Herein, the ability of gamma irradiation to enhance photoluminescence properties graphene quantum dots (GQDs) was investigated. Different doses γ-irradiation were used on GQDs examine way in which their structure and optical can be affected. The yield increased six times for irradiated with high compared nonirradiated material. Both lifetime values band gap dose applied irradiation. In addition, exploitation gamma-irradiated as photosensitizers examined by monitoring production singlet...
The near-infrared luminescence of Ca6Ba(PO4)4O:Mn5+ is demonstrated and explained. When excited into the broad strong absorption band that spans 500-1000 nm spectral range, this phosphor provides an ultranarrow (FWHM = 5 nm) emission centered at 1140 originates from a spin-forbidden 1E → 3A2 transition with 37.5% internal quantum efficiency excited-state lifetime about 350 μs.
