31. Their absorption peaks at ~ 630 nm and luminescence at ~ 650 nm. 32. Other uses include applications in colorimetry, crystallography, luminescence and spectrophotometric analysis. 33. No excitonic luminescence can be produced in metallic tubes. 34. Luminescence is under circadian regulation, peaking at night.35. The creature's design included bio-luminescence from the initial concepts. 36. The corresponding luminescence flux is proportional to the temporal change in photon number, 37. Using special filters, Frankel photographed the experiment, and showed the luminescence directly. 38. That confinement produced the room-temperature luminescence . 39. The Glimpse product line includes Luminescence Collection, Mineral Treatment, and Mangosteen Oils. 40. Negative luminescence has also been observed in semiconductors in orthogonal electric and magnetic fields.
