Label-Free Ag+ Detection by Enhancing DNA Sensitized Tb3+ Luminescence
In this work, the effect of Ag⁺ on DNA sensitized Tb(3+) luminescence was studied initially using the Ag⁺-specific RNA-cleaving DNAzyme, Ag10c. While we expected to observe luminescence quenching by Ag⁺, a significant enhancement was produced. Based on this observation, simple DNA oligonucleotide homopolymers were used with systematically varied sequence and length. We discovered that both poly...
متن کاملSynthesis and luminescence properties of YF3:Ce3+/Tb3+ nanocrystals.
YF3:Ce3+, YF3:Tb3+, and YF3:Ce3+/Tb3+ nanocrystals were synthesized by an ethylenediaminetetraacetic acid (EDTA)-assisted hydrothermal method and characterized by X-ray diffraction and scanning electron microscope. In the excitation spectra, there is one broad excitation band at 285 nm for YF3:Ce3+ and 255 nm for YF3:Tb3+, which are related to the f-d excitations of the Ce3+ and Tb3+ in the hos...
متن کاملGreen-Emitting Gd3Ga5O12: Tb3+ Nanoparticles Phosphor: Synthesis, Structure, and Luminescence
Nano- and microceramics of Gd3Ga5O12 garnet doped with 1 mol % Tb3+ ions were synthesized via co-precipitation and high-temperature solid-state reaction methods. X-ray diffraction measurements confirmed the formation of the garnet structure with Ia3d space group in all investigated samples. Atomic force microscopy surface images and grain-size distribution diagrams of Gd3Ga5O12: 1 mol % Tb3+ na...
متن کاملUpconversion Luminescence Sensitized pH-Nanoprobes.
Photon upconversion materials, featuring excellent photophysical properties, are promising for bio-medical research due to their low autofluorescence, non-cytotoxicity, low photobleaching and high photostability. Upconversion based pH-nanoprobes are attracting considerable interest due to their superiority over pH-sensitive molecular indicators and metal nanoparticles. Herein, we review the adv...
متن کاملUV-Vis Absorption and Luminescence Spectrum of LAS: Tb3+/Gd3 as a Laser Material (TECHNICAL NOTE)
This article discusses details study on crystallization , optical properties of Li-Al-Si-La glass containing nanocrystalline LaF3.and their optical energy gaps. The Urbach energy of glass samples was evaluated. By using (2% mole) Tb the green–blue range emission occurred, while by accumulation 1% mole Gd beside Tb, the indigo emission intensity (418 to 441 nm) increased.
