Abstract

Abstract: Ultrasensitive and sustainable near‐infrared (NIR)‐emitting piezoluminescence is observed from noncentrosymmetric and ferroelectric‐phase Sr3 Sn2 O7 doped with rare earth Nd 3+ ions. Sr3 Sn2 O7 :Nd 3+ (SSN) with polar A21 am structure is demonstrated to emit piezoluminescence of wavelength of 800–1500 nm at microstrain levels, which is enhanced by the ferroelectrically polarized charges in the multipiezo material. These discoveries provide new research opportunities to study luminescence properties of multipiezo and piezo‐photonic materials, and to explore their potential as novel ultrasensitive probes for deep‐imaging of stress distributions in diverse materials and structures including artificial bone and other implanted structures (in vivo, in situ, etc). Abstract : Ultrasensitive and sustainable near‐infrared‐emitting piezoluminescence is successfully realized from noncentrosymmetric and ferroelectric‐phase Sr3 Sn2 O7 doped with rare earth Nd 3+ ions. The breakthrough provides new research opportunities to study multipiezo and piezo‐photonic materials, and to explore their potential as novel ultrasensitive probes for deep‐imaging of stress distributions in diverse materials and structures (on‐site, in vivo, etc.).
