Abstract:
This paper studied the mechanoluminescence of the CaAl 2 Si 2 O 8 :Eu 2+ x , Dy 3+ y phosphors. The crystal structure, photoluminescence (PL) and mechanoluminescent intensity of the phosphors were investigated. The emission peak of CaAl 2 Si 2 O 8 : Eu x 2+ had a redshift from 418 nm to 428 nm due to the increase of the crystal filed intensity around Eu 2+ with the increase of Eu 2+ ion content. The ML (mechanoluminescence) emission of CaAl 2 Si 2 O 8 :Eu 0.01 and CaAl 2 Si 2 O 8 :Eu 2+ 0.01 , Dy 3+ 0.02 can be seen by the naked eyeswhen compressive loads were appliedon the samples. Whats more, the addition of Dy 3+ can increase the ML intensity of CaAl 2 Si 2 O 8 :Eu 0.01 . The ML and PL spectra of the sample CaAl 2 Si 2 O 8 :Eu 2+ 0.01 , Dy 3+ 0.02 are identical, located at 428 nm.
