AND IT WORKS!

A brand new thermofluorescent compound what emits a much brighter color when cooled down to circa -100 °C. On the first pics there is a filter paper with compound A in an α and in a ß crystal form. The α form emits a yellow and the ß emith a green color. Same compound, with a similar crystal form. When it’s cooled down with a small amount of liquid nitrogen (seen on the gifs) the intensity of the emitted light increases +100 fold compared to the room temperature emission with a quite similar wavelenght. On the last picture the cooled filter papers are seen when cooled down to -100 °C.

SCIENCE!
