| 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.
