THERMOLUMINESCENCE OF THE FILMS, NANOCOMPOSITES AND SOLUTIONS OF THE SILICON ORGANIC POLYMER POLY(DI-n-HEXYLSILANE)
Abstract
A comparative study of low temperature thermoluminescence (5-120 K) of silicon organic polymer poly(di-n-hexylsilane) films, nanocomposites (when the polymer is introduced into nanopores of silica МСМ-41 and SBA-15 with diameter of pores 2.8 and 10 nm) as well as solutions of polymer in tetrahydrofuran with different concentration from 10-3 to 10-5 mol/L was carried out. It was shown the possibility to control the number of traps for charge carriers, as well as their energy distribution by changing the diameter of silica nanopores. It is established that maxima and half-widths of the thermoluminescence curves of nanocomposites significantly depend on the pore diameter of the nanoporous silica. This result agrees with the data obtained in the investigation of polymer solutions. In the nanocomposite with a minimum pore diameter (2.8 nm), the number and depth of the traps as well as dispersion of their energy are significantly reduced in compare to their values in the polymer film .
