A study of the fluorescence spectra and dielectric properties of HDPE + x vol % TlGaSe2 composites

The results of studying the fluorescence spectra of HDPE + x vol % TlGaSe 2 ( x = 0, 1, 5, 10, and 20) composite materials in the wavelength range of 400–600 nm are described. The fluorescence effect is revealed, and the wavelength-dependent qualitative relationship between the composition and the fluorescence spectrum of the composite is found. The temperature dependences of the dielectric permeability and the dielectric loss tangent of the HDPE + x vol % TlGaSe 2 ( x = 0, 1, 3, 5, 7, and 10) composites in the temperature range of 300–500 K are studied.
