Měření optických vlastností luminoforových filmů nanesených na podkladu z polydimethylsiloxanu

Abstract

The purpose of this bachelor thesis is to create samples of thin film of the luminescent layer applied to pure polydimethylsiloxane (PDMS) and then to examine properties of this layer composed of luminophore and PDMS matrix. The luminophore was excited by a blue LED and we recorded the spectrum and the correlated color temperature (CCT) of the resultant light. At the same time, we were interested in how these characteristics will affect the change in luminophore concentration in the PDMS matrix, and we also determined whether the measured values of CCT would change when the sample temperature changes. For this bachelor thesis we needed a blue LED, measured samples, power supply, multimeter, electric furnace in which We heated individual samples, attenuator, spectrometer, optical cable, Thorlabs fastening structures and SpectraSuite software installed on a personal computer.
