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 particles to obtain stroboscopic fluorescence images of shocked sand-like media. Shock effects on microstructured media and micropressure distributions can be determined from shock-induced emission intensity loss, with high time and space resolution.
