Abstract

This paper presents the model of surface temperature variations, resulting from the photothermal effect induced in a ?thin film ? highly absorbing surface layer? structure, where the thin film is irradiated. The influence of the optical absorption coefficient and sample thickness on the induced temperature gradient is analyzed. It is shown that, depending on the product of these parameters (optical absorbance) in the described structure, the phenomenon of inverse temperature gradient can occur, further influencing the direction and the magnitude of thermoelastic displacement.

非辐照表面光吸收剂对薄膜中光热效应引起的温度梯度的影响
本文提出了薄膜中光热效应引起的表面温度变化模型。高吸水性表层?结构,其中薄膜被照射。分析了光吸收系数和样品厚度对诱导温度梯度的影响。结果表明,根据所述结构中这些参数(光学吸光度)的乘积,可以发生逆温度梯度现象,从而影响热弹性位移的方向和大小。
