The photoinduced dipole force(Pi DF) is an attractive force arising from the Coulombic interaction between the light-induced dipoles on the illuminated tip and the sample. It shows extreme sample-tip distance and refractive index dependence, which is promising for nanoscale infrared(IR) imaging of ultrathin samples. However, the existence of Pi DF in the mid-IR region has not been experimentally demonstrated due to the coexistence of photoinduced thermal force(Pi TF), typically one to two orders of magnitude higher than Pi DF. In this study, we demonstrate that, with the assistance of surface phonon polaritons, the Pi DF of c-quartz can be enhanced to surpass its Pi TF, enabling a clear observation of Pi DF spectra reflecting the properties of the real part of permittivity. Leveraging the detection of the Pi DF of phonon polaritonic substrate, we propose a strategy to enhance the sensitivity and contrast of photoinduced force responses in transmission images, facilitating the precise differentiation of the heterogeneous distribution of ultrathin samples.

在吸收峰范围内,单位波长吸光度的变化幅度与被测物浓度存在一定关系,建立了基于此关系的单位波长吸光度改变量-分光光度法(ACW-S法),并探讨了其在减小样品浊度对检测结果影响方面的作用。以环境水体中铬(Ⅵ)的检测为例,验证了ACW-S法的可行性。以方法检出限、准确度和精密度为考量因素,对拟合波长范围进行了筛选,共筛选出包括570~590nm波段在内的共13个波段,在这13个波段中,铬(Ⅵ)校准曲线的线性范围介于5.0~300μg/L之间,方法检出限在0.7~1.0μg/L范围,直接测定实际样品所得加标回收率为80.0%~116%(加标的质量浓度为10.0μg/L和20.0μg/L)。ACW-S法能减小样品浊度带来的正干扰,对于显色后在750nm处的吸光度小于0.300的样品均适用,并能显著降低样品浊度对检测结果的影响,配合过滤法或浊度补偿法,可进一步提高检测效果。
