Phosphorus does not glow from heat, and is somewhat dangerous to use. I'm not sure if you want to be able to visualize the circuit as a troubleshooting aid. If this is the case, digital cameras have sensitivity into the infra-red, and you might find that a camera will let you see what's getting hot.

If you want to be traditional, turn off power and see which component burns your finger.
