Spectra of photoluminescence of carboncontaining nanostructured objects

Abstract

It is discussed the possible mechanism of photoluminescence of such objects as carbon quantum dots, layers of amorphous hydrogenated carbon, and the natural biopolymer – native collagen. Recently in some researches were observed the interesting features of photoluminescence of carbon quantum dots . The features were discovered in comparison of photoluminescence in layers of amorphous hydrogenated carbon and in natural biopolymer – native collagen. This article describes a method of experimental study of the absorption spectra, excitation and photoluminescence characteristics of collagen with using modern measuring devices. Fixed excitation of photoluminescence was carried by an argon laser. A nitrogen laser was used for pulsed excitation. It is found that some properties of the luminescent radiation may be explained by assuming the nature of excimer photoluminescence collagen.
