‘Naturally Insulating’ Material Emits Pulses of Superfluorescent Light at Room Temperature
Phys.org
“When we excited the material at different laser intensities, we found that it emits three pulses of superfluorescence at regular intervals for each excitation,” says Shuang Fang Lin, associate professor of physics at NC State and co-corresponding author of the research. “And the pulses don’t degrade—each pulse is 2 nanoseconds long. So not only does the UCNP exhibit superfluorescence at room temperatures, it does so in a way that can be controlled.”
