Constant exposure to infrared light will make green ZnS glow for much less time, especially as IR intensity increases. In other words, IR can quickly release the stored photons in ZnS. IR can be used as a glow eraser.

The ZnS you have may be good enough,
or the phosphor used in old radar screen tubes maybe what you want.

You need a product called Zinc Orange from Glow Inc. (www.glowinc.com) It is bright initially, but fades very quickly.
