Paper Abstract

A new technique proposed for detection of non-basic phases (percolative semiconductor nanoclusters incorporated into intrinsic cages of zeolites) in samples, which are the mixture of these nanoclusters with crystals of micron size. This technique is based on studying of the photothermal (PhT) spectra obtained by gas-microphone method of signal detection. The main idea consists in taking into account contribution to the PhT response from so-called interstitial gas filling the pores inside samples based on zeolite. The method proposed lets to improve the sensitivity of PhT spectroscopy up to detection of quantum-size phases in the objects of experiment.
