Description
Summary:The force‐induced light‐emitting phenomenon in polymer composites plays an important role in the soft electronic field due to its display function. Here, a magnetic‐force‐induced‐luminescence (MFIL) effect is reported in ZnS:Cu particle‐doped polydimethylsiloxane incorporated with a NdFeB magnetic tip mass for real‐time incident magnetic field strength light‐emitting display. Investigations show that the luminescence intensity increases nearly linear in response to the applied AC magnetic field, HAC; meanwhile, the minimum HAC for inducing MFIL is as low as 0.1 mT (1 Oe) at the resonance. The MFIL effect is 1000 times better and more energy‐efficient than the best result published previously. The findings, thus, indicate that the MFIL effect could serve as an effective method for light‐emitting display triggered by HAC; MFIL essentially originates from the donor–acceptor recombination between shallow donor level and the t2 level of Cu2 in ZnS:Cu semiconductor particles. The present results could, thus, provide a viable pathway toward multifunctional flexible electronic designs and applications, especially toward those for the real‐time visualization of remote magnetic field sensing. Magnetic‐force‐induced‐luminescence (MFIL) coupling effect is based on a flexible ends‐clamped structure composite consists of ZnS:Cu particle embedded polydimethylsiloxane and a NdFeB magnetic tip mass. This MFIL system is a promising candidate for real‐time magnetic visualization as well as flexible remote magneto‐optic sensing device without making electric contact and power supply.
