Rapid, multiplexed, sensitive and specific identification and quantitative detection of nitric oxide (NO) are in great demand in biomedical science. Herein, a novel multifunctional probe based on the intramolecular LRET (luminescence resonance energy transfer) strategy, TRP-NO, was designed for the highly sensitive and selective ratiometric and luminescence lifetime detection of lysosomal NO. B...

Owing to high quantum efficiency, adjustable composition and antioxidation properties of oxynitride phosphors, extensive investigations have focused on their photoluminescence properties under low-energy light excitation (UV or blue light). However, the vacuum ultraviolet (VUV) luminescence properties of oxynitride phosphors are rarely researched. Present work studies the structure and VUV lumi...

In this study, multifunctional Fe₃O₄@SiO₂@GdVO₄:Dy3+ nanocomposites were successfully synthesized via a two-step method. Their structure, luminescence and magnetic properties were characterized by X-ray diffraction (XRD), scanning electronic microscope (SEM), transmission electron microscopy (TEM), photoluminescence (PL) spectra and vibrating sample magnetometer (VSM). The results indicated tha...

We have conducted a systematic study of the bandedge and infrared luminescence properties of Er-implanted GaN thin films. The GaN films, grown by metalorganic chemical vapor deposition, were co-implanted with Er and O ions. After implantation, the implanted samples were furnace annealed at temperatures up to 1100°C. Following annealing, the samples were examined for both bandedge luminescence a...

The introduction of bulky tert-butyl substituents into smectic liquid-crystalline 9,10-bis(phenylethynyl)anthracene derivatives influences excimer structures and luminescence properties.

In this investigation, Eu3+ doped YVO4 /YBO3 phosphors were synthesized individually by conventional solid state method at 1100 °C under atmosphere condition. Meanwhile, different amounts of LiClwere used as the flux compound to modify the morphology of the phosphor particles and also final luminescence properties. It was concluded that even small amounts of fluxes play a vital role in the grow...

Zirconia is a relatively new material with many promising practical applications in medical imaging, biolabeling, sensors, and other fields. In this study we have investigated lanthanide and niobium doped zirconia by luminescence and XRD methods. It was proven that charge compensation in different zirconia phases determines the incorporation of intrinsic defects and activators. Thus, the struct...

Luminescence is now extensively used in biology since it constitutes as a very sensitive way of investigations. Several applications of fluorescence concern immunoassays, DNA hybridization, protein interactions, cell imaging, Lab-on-chip etc.;; As non biological fluorescent probes, organic dye molecules and semiconductors quantum dots are the most popular. However, they suffer from drawbacks wh...

We developed a novel spin-labeled terbium complex Tb(3+)/cs124-DTPA-TEMPO (1) by covalently labeling a nitroxide radical on the terbium complex for monitoring free radicals of various areas. This lanthanide complex probe shows a high EPR signal which resulted from the nitroxide radical moiety, and is weakly luminescent which resulted from the intramolecular quenching effect of the nitroxide rad...
