Teplotní stabilita luminoforů v PDMS matrici pro zářivé zdroje

Abstract

The purpose of this diploma thesis is to examine the thermal stability of phosporus within polydimethylsiloxane (PDMS) matrix for luminous sources. For this thesis it is necessary to create a matrix from the PDMS mixed with phosporus to generate while light with blue laser diode and to measure and analyze parameters such as intensity, wavelenght, color rendering index and correlated colour temperature. In order to successfully measure and analyze these parameters following equipment is required. PDMS samples mixed with phosporus, blue laser, PDMS material with hardener, laboratory tools, device for thermal calibration, thermometer, spectrometer and software for the spectrometer.
