Gigantic directional asymmetry of luminescence in multiferroic CuB2O4 [PDF]
Phys. Rev. B 93, 201109 (2016), 2016 We report direction dependent luminescence (DDL), i.e., the asymmetry in the luminescence intensity between the opposite directions of the emission, in multiferroic CuB2O4. Although it is well known that the optical constants can change with the reversal of the propagation direction of light in multiferroic materials, the largest asymmetry in the ...

Luminescence Decay and the Absorption Cross-Section of Individual Single-Walled Carbon Nanotubes [PDF]
Phys. Rev. Lett. 101, 077402 (2008), 2009 The absorption cross section of highly luminescent individual single-walled carbon nanotubes is determined using time-resolved and cw luminescence spectroscopy. A mean value of 1x10-17 cm2 per carbon atom is obtained for (6,5) tubes excited at their second optical transition, and corroborated by single tube photothermal absorption measurements ...

Luminescence from cavitation bubbles deformed in uniform pressure gradients [PDF]
Physical Review E 96(3) 033114 (2017), 2017 Presented here are observations that demonstrate how the deformation of millimetric cavitation bubbles by a uniform pressure gradient quenches single collapse luminescence. Our innovative measurement system captures a broad luminescence spectrum (wavelength range 300-900 nm) from the individual collapses of laser-induced bubbles in water.
