Hey, try heating up that ruby! It'll turn darker as the bandgap moves toward the IR.
You can shift your dip with a hair drier.
It should move from ~1.15eV at room temp 75F/25C to ~1.10eV at 120F/50C, which should be about 35nm longer.
- anfractuosity 3y agoOoh, cool! Will definitely have to give that a shot.
- kurthr 3y agoUse liquid nitrogen and you can get it to turn light pink!
