Luminescence properties of phosphors for highpower LED applications
Rejman, Martin ; Nikl, Martin (advisor) ; Mareš, Jiří A. (referee) ; Nejezchleb, Karel (referee)
For selected YAG:Ce sample the temperature dependent absorbtion and emission spectra were measured and used to simulate white LED behavior. Various CIE-xy dependencies were observed. Sample surface scaterring parameters were calibrated using a custom-made automated goniospektrometer, which provided measured data with fine accuracy. Finally, the measured data were used to construct a Geant4 simulation to optimize two light devices for output intensity and target CIE-xy coordinates. Powered by TCPDF (www.tcpdf.org)
