Article Preview

Strongly adherent SrAl2O4:Eu films were fabricated on the rough surface of an alumina substrate by a combination of the RF magnetron sputtering technique and a post-annealing treatment. A crystalline SrAl2O4:Eu2+ film was achieved after annealing at 1000°C in reduced atmosphere and it exhibit a intensively green PL and triboluminescence (TL) while an as-deposition film showed the amorphous state and weakly red photoluminescence (PL). It was found that the fabricated films possessed a strong durability of a friction, exhibiting no peeling, cracking, and breaking in the films after TL measurements. These results will facilitate a development of novel TL skin sensors.
