This article presents the results of comparative investigations of thermal parameters of hybrid sol–gel coatings (named TMZ) prepared from tetraethyl orthosilicate and organically modified 3-methacryloxypropyltrimethoxysilane. The coatings were prepared with the addition of zirconium(IV) tetrapropoxide chelated with methacrylic acid. Two series of samples were investigated: the first series, TMZ-I, TMZ-II and TMZ-III, with different amounts of zirconium, and the second series, TMZ-I/Ce, TMZ-II/Ce and TMZ-III/Ce, with the addition of cerium nitrate. The influence of the amount of zirconium and cerium on the thermal parameters of the sol–gel coatings was next analyzed. Two non-destructive and photothermal techniques were used for this purpose: photothermal radiometry (PTR) and beam deflection spectroscopy (BDS). The thermal diffusivity and conductivity of the coatings were extracted from the frequency experiments and are presented and discussed. The two-layer model was applied to interpret the photothermal spectra. The results obtained using these two techniques are compared and discussed.

In this paper results of investigations of Au 2+ and Ge + ion-implanted silicon samples with the use of the nondestructive frequency and the space domain photo thermal infrared radiometry (PTR) method are presented. Frequency amplitude characteristics and spatial amplitude distributions of the PTR signal for the implanted silicon samples were measured and analyzed. Measurements have been performed for several wavelengths of the exciting light. The dependence of the amplitude of the PTR signal on the optical and recombination parameters of the implanted layers has been analyzed experimentally and theoretically and discussed. The objective of this work is to present the possibilities of investigations of the influence of the high energy and high dose implantation process into silicon on the optical and recombination parameters of implanted silicon with the use of the frequency and spatial domain PTR method. Observed changes in the measured signal have been explained by simultaneous changes of values of the optical absorption coefficient and carriers lifetime of implanted layers.
