Which somewhat gets back to my original question. I thought that the bandgap of the material set the photon frequency, and the current magnitude changed the number of photons per unit time, basically made it brighter or dimmer. How does changing the current change the output wavelength of a solid state diode emitter? Is there a second order effect, or have I misunderstood the physics of light emission in semiconductors? -- Chris Caudle _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
