56638 实验发现,外加零偏压时,共混器件中光致发光磁效应(magneto-photoluminescence, MPL)在不同温度下均为类"W"线型,光电流的磁效应(magneto-photocurrent, MPC)则出现了没有报道过的类"M"线型,且MPC高场效应与低场效应随温度有不同的变化规律; It then systematically measured the photoluminescence and photocurrent magnetic field responses of the devices with different blending proportions at different temperatures and applied voltages. The study found that the temperature-dependent magneto-photoluminescence (MPL) curves of the blending devices presented a W-like line-shape under zero bias voltage, while the magneto-photocurrent (MPC) curves showed an unreported M-like line-shape.
56639 同时,在外加偏压调控光电流为正的情况下,共混器件中的MPC幅值出现了正负转变. The temperature dependences of high field effect and low field effect for the MPC curves demonstrated different evolution regulations. At the same time, the amplitudes of MPC curves changed from positive to nega?tive signs with positive bias current.
56640 分析结果表明,器件中类"W"型曲线是受磁场调控的单重态激子分裂(singletfission, STT)过程引起的,而类"M"型MPC的低场上升部分是3TPYMB分子中极化子对间的系间窜越(intersystem crossing, ISC)过程的作用,高场下降部分则是由三重态激子–电荷湮灭(triplet-charge annihilation, TQA)过程所引起, MPC幅值的正负转变与外加偏压强度有关. By analyzing these interesting variations in the curve line-shapes, we found that the W-like line-shape curves are caused by a magnetic-field-mediated singlet fission (STT) process. The rise in the MPC curve at low magnetic field can be attributed to the effect of the intersystem crossing (ISC) process, and the fall in the MPC curve at high magnetic field is caused by the triplet-charge annihilation (TQA) process. The positive to negative change in MPC amplitude is related to the intensity of electric injection carriers.
