| The light is often under the fish's nervous control, and after death the ability to luminesce disappears rapidly. |
| He found that phosphors luminesce brightly in the invisible region beyond violet and thus discovered ultraviolet radiation. |
| She does not recognize the pattern of bars that luminesce on the gel until she has stared at it for a full minute. |
| In the case of some of these oxidizers pyrogallol will luminesce in dilute concentrations but not in strong. |
| Also, dilute pyrogallol will luminesce with a dilute solution of oxidizer but not with a concentrated solution of oxidizer. |
| On the other hand, a great many forms are able to luminesce quite independently of previous illumination. |
