I would suggest using Attenuated Total Reflectance (ATR) for thin film analysis. For ATR analysis you can use whatever substrate you are depositing on by using a fresh substrate without the thin...

2013年5月15日 · Fourier transform infrared (FTIR) spectroscopy in the attenuated total reflectance mode (ATR) was used to characterise SiO x H y thin films deposited on either polypropylene foil or silicon wafers through a cold atmospheric plasma discharge.

the Fourier transform infrared (FTIR) technique is the speed of the measurement. Other benefits are that the FTIR thickness measurement is non-destructive and reproducible, lends itself to automation, and is operator independent. Raw data from an FTIR spectrometer generally take the form of an interferogram, which can be described as a summation of

2019年4月30日 · We present nanomechanical infrared spectroscopy (NAM-IR), which enables the measurement of a complete infrared fingerprint of a polyvinylpyrrolidone (PVP) layer as thin as 20 nm with an SNR of 307. Based on the characterization of the given NAM-IR setup, a minimum film thickness of only 160 pm of PVP can be analyzed with an SNR of 2.

FTIR spectroscopy reveals that grazing angle ATR enhances ultra-thin film analysis sensitivity compared to transmission, especially near the critical angle.

1991年1月1日 · This review will discuss the techniques for and applications of FTIR spectroscopy to the analysis of thin films. In the FTIR literature the term "thin film" is used for a variety of film types. These include organic polymer films, Languimer-Blodgett films, thin liquid films, and adsorbents on metal surfaces, to name only a few.

2023年1月1日 · Dryfilm FTIR showed higher accuracy for prediction of average molecular weight (AMW) in liquid protein hydrolysates. FTIR can be used to predict the AMW of industrial protein hydrolysates with a sensitivity of high industrial relevance. ATR proved to be a more reliable method for the prediction of Brix values.

This FTIR Talk Letter introduced Reflection absorption spectroscopy (RAS) and the single-reflection ATR technique as methods for measuring thin film samples. RAS is unsuitable when the substrate is non-metallic, but thin film on a metallic substrate can …

2024年9月3日 · Fourier-transform infrared (FTIR) spectroscopy is commonly used to analyze organic compounds synthesized by chemists, but reflectance-based FTIR methods can also be a powerful technique for analyzing thin films on reflective substrates.

2020年12月23日 · In this work, various types of thin films were prepared via physical and chemical deposition techniques. The Fourier transform infrared spectroscopy (FTIR) was used to identify functional groups...
