Phosphorescent Phenomena Experiments with Different Wavelengths and Temperatures

This is a quick rough video on some more DIY experiments with phosphorescent materials and a little follow up to a really old video of mine. The original video was on the ability to erase the glow from phosphorescent materials with an IR and Red laser pointer. In the previous video I was a bit confused at why this happened. There was an article sent via comments and it's liked below for your reading pleasures. However I was not completely satisfied at it's explanation. Because of that I started experimenting with different wavelengths of Lasers and the temperatures of my materials and found a wide array of behavioral differences. The original mechanism I saw was probably due to the heat generated by the laser in the material causing the glow to release quicker thus leaving a darker area after exposure. These are all experiments you can also perform as well. I found it quite interesting to see these effects myself. A much more detailed video on both florescence and phosphorescence will be done in the future with many more experiments and explanations in the science behind the mechanisms. I thought this was a neat little share for the time being.https://physics.stackexchange.com/questions/22691/how-does-infrared-light-erase-phosphorescence-on-zinc-sulfide
