Light Conversion using Perovskite Quantum Dots
This tutorial presents the main properties of quantum dots and gives an example of how to characterize films with embedded quantum dots using angular resolved spectroscopy.
Angular Resolved Photoluminescence and Electroluminescence of light emitting materials
Setfos can analyze angular-dependent PL data collected by Phelos to get information about the properties of an organic emitter, such as the orientation of the dipoles and the width of the emission zone. With this analysis, we are able to optimize the characteristics of our OLEDs for high EQEs.
Impact of Photon Recycling on the Efficiency of Light Extraction in Metal Halide Perovskite Light Emitting Diodes
We introduced a theoretical treatment of photon emission and recycling in optoelectronic semiconductor devices that is free of non-physical divergencies. Here, we now show the application of this framework to the assessment of the impact of PR on the light extraction efficiency in perovskite LEDs. This treatment goes from the analysis of contributing photonic modes in single emitter slab configurations to the evaluation of the external LED quantum efficiency in realistic device stacks.
