Enhancement of adhesion and triboluminescence of ZnS : Mn films by annealing technique

Highly triboluminescent and strongly adherent ZnS films doped with Mn (ZnS: Mn) were fabricated on glass substrates by ion-plating and a post-plating h eat treatment in a vacuum-sealed quartz glass tube. A crystalline ZnS:Mn fi lm was prepared from a high-crystallinity ZnS:Mn pellet by ion-plating. The crystallinity and the friction-induced photon-emitting capability (tribolu minescence) of the films were greatly enhanced by a post annealing in vacuu m-sealed quartz glass tube. Of greater interest, we found that this anneali ng treatment strengthened the bond to the glass substrate together with enh ancing the endurance to friction, which greatly enhanced its practicability to act as a stress/friction sensor for various applications.
