Застосування середовища R для аналізу спектроскопічних даних

Abstract

Recently the fluorescent microscopy of biological objects with doped luminescent nanoparticles as biomarkers has became rapidly developing technology. In this paper, we have synthesized the microparticles of YVO4:Bi3+ by the method of solid phase synthesis with different concentrations of Bi. For processing and analysis of experimental data we used “prospectr” R-package, namely for data smoothing and noise elimination. As a result, we can say that with increasing of concentrations of Bismuth ions in the matrix YVO4, the edge of luminescence excitation is shifting to the longer wavelengths 370nm. This fact allows us to use such luminescent nanoparticles as biomarkers. The R packages for spectroscopy in physics research of luminescence appear to be more useful than standard methods of computer research.
