    In this study, 0.96(K0.48Na0.52)(Nb0.95-xTa0.05Sbx)O3-0.04Bi0.5(Na0.82K0.18)0.5ZrO3 (0.96KNNTSx-0.04BNKZ, x=0.03, 0.04, 0.06, 0.07) lead-free transparent piezoelectric ceramics were prepared, and the effects of Sb doping levels on their piezoelectric properties and optical transparency were examined. All samples exhibit a perovskite structure. With increasing Sb content, both piezoelectric performance and transparency improve. Notably, at x=0.04, the piezoelectric coefficient reaches 240 pC/N, with an optical transmittance of 31.5% at 780 nm. This study demonstrates that compositional design can achieve enhanced transparency and high piezoelectric performance in KNN-based lead-free ceramics, offering significant potential for applications in optoacoustic imaging and transparent transducers.
