Keywords:Near-infrared Mechanoluminescence Material

Mechanoluminescence is a type of luminescence induce by mechanical action on solids, which is expect to be applied in various fields, especially, the NIR ML material can be utilized in many areas with good bio-permeability, and thus it can be used for application to medical examination, etc. In this work, we synthesized NIR ML material Sr₃Sn₂O₇:Nd³⁺that exhibited NIR luminescence. We also investigated the transmission through the biological tissue from the NIR ML material and the water-resistant ability of Sr₃Sn₂O₇:Nd³⁺.
