摘要

本文介绍了低钛酸铅(PT)掺杂的电致伸缩热压铌酸铅镁(PMN)作为候选透明换能器材料。我们制造了透明高频单元件换能器,并对其光学、电学和声学特性进行了表征。PMN-PT由于其高机电效率和偏压灵敏度,可能比其他换能器材料(如铌酸锂)具有灵敏度优势。在532 nm波长处测量到该换能器的透明度为~ 67%,在直流偏置电平为100 V时,最大机电系数为~ 0.68。在直流偏置电平为40 V时,光声脉冲响应的中心频率为~ 27.6 MHz,带宽为~ 61%。结果表明,新型透明换能器在未来的光超声和光声成像应用中具有广阔的前景。

Bias-sensitive transparent single-element ultrasound transducers using hot-pressed PMN-PT
Here we introduce electrostrictive hot-pressed lead magnesium niobate (PMN) with low lead titanate (PT) doping as a candidate transparent transducer material. We fabricate transparent high-frequency single-element transducers and characterize their optical, electrical, and acoustic properties. PMN-PT may offer sensitivity advantages over other transducer materials such as lithium niobate owing to its high electromechanical efficiency and bias-voltage sensitivity. The transparency of the fabricated transducer was measured ∼67% at 532 nm wavelength with a maximum electromechanical coefficient of ∼0.68 with a DC bias level of 100 V. The photoacoustic impulse response showed a center frequency of ∼27.6 MHz with a −6 dB bandwidth of ∼61% at a DC bias level of 40 V. Results demonstrate that the new transparent transducers hold promise for future optical-ultrasonic and photoacoustic imaging applications.
