英文摘要Cu12Sb4S13 has received great attention due to its remarkable thermoelectric properties among medium-temperature range. Herein, the effect of rare earth element Pr substitution at Cu site of Cu12Sb4S13 is comprehensively investigated. Heavy rare earth element Pr substitution can induce strong mass fluctuation and strain-field fluctuation, resulting in intense phonon scattering and decreased lattice thermal conductivity. Consequently, a low lattice thermal conductivity kappa(L) of 0.42 W m(-1) K-1 is obtained at 748 K in Cu11.7Pr0.3Sb4S13 sample. Additionally, the substitution of Pr for Cu can function as donors, tuning the hole concentration and optimizing the thermopower over the entire temperature range, with a maximum thermopower of 165 mu V K-1 at 748 K. Correspondingly, a peak ZT of similar to 0.9 is obtained at 748 K in Cu11.7Pr0.3Sb4S13 sample, due to the significantly reduced thermal conductivity and slightly enhanced power factor.
