Can light emitting diodes be used to generate UV wavelengths? That used to be a method for producing white LEDs - a blue LED and a fluorescent dye. It's not used anymore because of true white LEDs, and being able to package multiple wavelength LEDs on the same die. |

The Superconducting Super Collider: what went wrong? Specifically it was promoted by a Texan politician as a pork barrel project for his state, then in the next administration when the same politician was all for cutting government the backlash was to cut 'his' project in retaliation |
