• Symbiotic bacteria program daily rhythms in squid using light and chemicals

  Glowing bacteria inside squids use light and chemical signals to control circadian-like rhythms in the animals, according to a study to be published in mBio®. The Hawaiian bobtail squid, Euprymna scolopes, houses a colony of Vibrio fischeri bacteria in its light organ, using the bacteria at night as more

• Elemental and magnetic imaging using X-rays and a microscope

  A team of researchers has developed a new microscope that can image the elemental and magnetic properties of a wide range of energy-important materials that are used in devices such as solar cells and solid-state lighting. The imager is based on a technique known as X-ray excited luminescence micros more

• Nano 'pin art': NIST arrays are step toward mass production of nanowires
  

  NIST researchers grow nanowires made of semiconductors—gallium nitride alloys—by depositing atoms layer-by-layer on a silicon crystal under high vacuum. NIST has the unusual capability to produce these nanowires without using metal catalysts, thereby enhancing luminescence and reducing defects. NIST more

• Luminescence and site occupancies of Eu3+ in La2CaB10O19

  Eu3+-activated La2CaB10O19 phosphors with nominal chemical formulae La2-xEuxCaB10O19 and La2Ca1-2xEuxNaxB10O19 were prepared. The luminescence properties under VUV-UV excitation were investigated. Luminescence spectra reveal Eu3+ ions occupy both Ca2+ and La3+ sites in all samples. The O2- → Eu3+ ch more

• Highly efficient thermally activated fluorescence of a new rigid Cu(I) complex [Cu(dmp)(phanephos)]+

  The rigid [Cu(dmp)(phanephos)]+ complex displays high luminescence quantum yield of 80 % at ambient temperature. In contrast to the long-lived phosphorescence of 240 μs below T < 120 K with a radiative rate of kr = 3•103 s-1, the ambient-temperature emission represents a thermally activated delayed more

• Luminescence thermochromism of two entangled copper-iodide networks with large temperature-respondent emission shift

  The luminescence thermochromism properties of two entangled copper(I)-iodide coordination polymers formulated [Cu4I4(dmimpr)2]n (1) and [Cu6I6(dimb)3]n (2) (dmimpr = 1,3-di(2-methyl-imidazol-1-yl)propane, dimb = 1,4-di(imidazol-1-yl)butane) are reported. Upon cooling by liquid nitrogen, their solid- more
