Description
Summary:Clear magneto-light output is obtained from a fabricated three-phase composite of magnetostrictive, piezoelectric, and electroluminescent materials. Electrical charges, attributable to the magnetoelectric effect, are induced when a magnetic field is applied to the magnetostrictive/piezoelectric layers. These induced electrical charges result in a light signal emanating from the electroluminescent layer, thereby accomplishing a magneto-light effect. Increasing the strength of the applied ac magnetic field or the number of series-connected piezoelectric layers produces an enhanced magneto-light output. The magneto-light composite has potential applications in magnetic resonance imaging, optical monitoring of magnetic fields, magnetic/light sensing, and transducer technologies.
