hey!
Zinc sulphide fluoresces (gives out a photon of visible light) when it is hit by a charged particle. Covering the microscope lens with ZnS allowed the viewer to 'see' where the alpha particles hit (or at least count their impacts).

because zns is a fluorescent material hence it emits light when electron strikes which was useful during his experiment
