Mechanoluminescence (ML) material is a novel functional material, showing a great potential on stress distribution of buildings, machine parts and other solid components. Novel ML materials NaAlSiO4:Eu2+,Ln3+(Ln=Ho, Nd, Dy) were prepared by a solid-state sintered method, And their microstructure, ML and PL properties were investigated. ML spectra were similar to the PL spectra with an emission band at 550nm, originating from transition 5d-4f of Eu2+, and other three emission peaks at 611 nm, 590nm and 578 nm, respectively ascribed to the transitions of 5D07F2, 5D07F1 and 5D07F0 of Eu3+ ions. Thermoluminescence (ThL) was measured to characterize traps in NaAlSiO4:Eu2+,Ln3+(Ln=Ho, Nd, Dy). Diversity of ThL curves demonstrated co-doped Ln3+ change trap levels in NaAlSiO4:Eu2+.
