I was looking at a Jenkins projection television system thats a bit different using a light cell ..some information on the page said the chemical he used was carbon bisulphide but i think its a mistake its carbon Disulphide.

In fact theres even a you tube video how to make the stuff but sounds pretty nasty !!!
