Electroabsorption study of metal-to-ligand charge transfer in an organic complex of iridium (III).
PublikacjaW pracy zmierzono i zinterpretowano widmo elektroabsorpcji (EA) próżniowo naparowanych warstw organicznego kompleksu Ir(ppy)3, powszechnie stosowanego jako emiter fosforescencyjny w organicznych diodach elektroluminescencyjnych. Analiza widma EA potwierdziła fakt,że niskoenergetyczne stany elektronowe tego kompleksu związane są z przeniesieniem ładunku metal-ligand.

Automatic Correction of Non-Anechoic Antenna Measurements Using Complex Morlet Wavelets
PublikacjaReal-world performance of antennas is normally tested in anechoic chambers (ACs). Alternatively, experimental validation can be performed in non-anechoic environments and refined in the course of post-processing. Unfortunately, the existing methods are difficult to setup and prone to failure. In this letter, a wavelet-based framework for correction of non-anechoic antenna measurements has been proposed. The method involves automatic...
