The emission lifetimes of rhodamine 6G (R6G) were measured under shock compression to 9.1 GPa, with the dual intents of better understanding molecular photophysics in extreme environments and assessing the usefulness of fluorescence lifetime microsco

We have used fluorescent probes for time-resolved microscopy of shocked particulate media. By embedding rhodamine 6G (R6G) dye in silica nano- and micro-particles, we have created superemissive ultrafast pressure probes. We used silica-embedded dye p

We are developing fluorescent probes to obtain dynamic two-dimensional pressure maps of shocked microstructured materials. We have fabricated silica nano-or micro-spheres doped with rhodamine 6G dye (R6G) which fluoresce strongly, and which may be di

Here, we report efficiencies up to 112,000 plates per meter (a reduced plate height, h, of 2.22) for RP, carbon/nanodiamond/aminopolymer particles using conventional injection conditions in HPLC. This efficiency greatly exceeds our best previously re

The nanometer size of CdTe quantum dots (QDs) and their unique optical properties, including size-tunable narrow photoluminescent emission, broad absorption, fast photoluminescence decay, and negligible light scattering, are ideal features for spectr

Experiments were performed to study the response to shock compression of rhodamine 6G (R6G) dye encapsulated in 1.25 μm diameter silica microspheres. When R6G was encapsulated in microspheres, the emission intensity under steady-state irradiation (t
