Inorganic materials which emit light when excited by ultrasound have garnered growing attention. While the phenomenon holds considerable potential for advanced sensing, damage detection, and remote illumination, it has so far been known only for crystalline and often opaque materials. Herein, persistent…
Abstract Light emission from CaZnOS:Nd 3+ by high‐intensity ultrasound excitation is demonstrated. Acoustic power and duty ratio enable simultaneous control of the degree of (local) thermo‐acoustic heating in isothermal or nonisothermal conditions. The Nd‐related photoemission provides direct thermometric…
An intense ultrasound‐induced luminescence (USL) from Cr 3+ ‐activated glass – ceramic composites, obtained by direct precipitation of nanoscale ZnGa 2 O 4 from silicate melts upon cooling, is reported. The USL band overlaps with the first near‐infrared transmission window of biological tissue and spans…
Mechanoluminescent (ML) materials, which generate light emission under mechanical stimulus, have attracted more and more attention in recent years due to their mechano-to-optical energy conversion capability. ML materials have been found to have huge potential in various field including force sensing,…
We report on the elastic properties of x MnO‐Al 2 O 3 ‐(6‐ x )SiO 2 manganese aluminosilicate glasses, in which pronounced exchange coupling and antiferromagnetic interaction occurs among the paramagnetic Mn 2+ ions. X‐ray absorption reveals a Mn‐O bond length of ∼2.1 Å, and a distance of ∼3 Å between…
