Now an exact and comprehensive characterisation of photoluminescent materials such as fluorescent probes, LED phosphors, organic metal complexes, OLED more
A fascinating and crucial ability of biological tissue, such as muscle, is self-healing and self-strengthening in response to damage caused by external forces. Most human-made polymers, on the other hand, break irreversibly under enough mechanical stress, which makes them less useful for certain cri more
Fluorescence usually entails the conversion of light at shorter wavelengths to light at longer wavelengths. Scientists have now discovered a chromophore system that goes the other way around. When excited by visible light, the fluorescent dyes emit light in the ultraviolet region. According to the s more
Many people know the effect from discos when “black light” makes clothes or writing boards glow. The reason for this are so-called fluorescent dyes. They send back part of the light they are exposed to in a slightly different way and thus glow. Particularly large fluorescent molecules are often inte more
Got a special someone you want to impress? Check out this life hack on how to turn white flowers into fluorescent masterpieces! more
Have you ever wondered about what makes a fluorescent color stand out so brightly from the rest? Today we’re digging into what makes them pop, and we’re going highlight some of the brilliant applications of fluorescence coming out of nanotechnology. more
The detection of SNPs (single nucleotide polymorphisms) is an important tool for researchers in order to find mutations in DNA sequences. In this application note we describe a homogeneous fluorescence assay based on PCR. The Amplifluor® S more
The method presented here for producing multifunctional Pyrenes, Perylenes and other homologue compounds provides a very flexible and effective route more
Design of experiments (DoE) is one of the most important techniques for systematic planning, execution and statistical evaluation of experiments. Although a DoE investigation is executable in one bioreactor, multi-bioreactor systems designed for pa more
If you’ve ever made a curry, you’ve likely used turmeric – you may even have some in your kitchen right now. It’s probably not the first thing that comes to mind when you think about doing chemistry, but there are actually some pretty neat chemistry tricks you can do with it! In this post, we take a more
Metal ions-doping is paid a little attention comparing with the nonmetallic-element doping to improve the fluorescence intensity of carbon dots (CDs). Herein, Fe2+-doped CDs was facilely synthesized at 80 °C instead of hydrothermal method for the first time. Fe2+ was confirmed to be the only definit more
A turn-on fluorescent probe (E)-4-(2-(1H-benzo[d]imidazol-2-yl)vinyl)-N,N-diphenylaniline (BVD) was facilely synthesized via the ethylene bridging of triphenylamine and benzimidazole. The probe exhibited strong emission enhancement in the vis-NIR fluorescence region at 605 nm with pKa 4.14 and linea more
Very short fluorescence lifetimes evidence ultrafast deactivation of photoexcited molecules. To unveil the underlying mechanism for two compounds exhibiting (sub)picosecond emission dynamics, we combine femtosecond fluorescence upconversion with high-pressure liquid-phase spectroscopy. For the triaz more
Organic light emitting diodes (OLEDs) are presently conquering the market for displays of smartphones and TVs. They also have a great potential in lighting applications. Current devices for the blue part of the visible spectrum lag behind their green and red counterparts in terms of efficiency and durability. more
Fluorescence Fluorescence is a luminescence that is mostly found as an optical phenomenon in cold bodies, in which the molecular absorption of a photon triggers the emission of another photon with a longer wavelength . The energy difference ... more
