Cathodoluminescence mapping with an EDX detector: principle, simulation and application
Abstract
The observation of cathodoluminescent (CL) emission in a scanning electron microscope (SEM) generally offers a wealth of information as it allows the study of materials on a nanoscale, thus separating effects which are disguised in macroscopic luminescence measurements. In combination with elemental analysis (e.g. EDX) or with structural analysis (e.g. EBSD), even more information can be extracted [1,2].Here we report on the use of the silicon detector, normally used for the energy-dispersive analysis of the characteristic x-rays, for the detection of (CL) light [3]. When visible light is absorbed by this detector, electron-hole pairs are generated which introduce a spurious signal in the low-energy part of the EDX spectrum. The intensity of this signal was studied as a function of the detector settings and the wavelength and intensity of the incoming light. This behaviour was then explained based on the working principle of the EDX setup and confirmed by numerical simulations with a purposely written software program. Although the detection of CL with the EDX detector can be a nuisance for elemental analysis, we show that the signal in the low-energy part of the EDX spectrum can readily be used to obtain CL mappings along with simultaneously recorded elemental mappings.We illustrate this CL mapping technique with experiments on both thin films and powders. The hydrolysis behaviour of blue-emitting BaAl2S4:Eu2+ thin films, which are used in flat panel electroluminescent displays, was studied. For several powder phosphors (Ca2SiS4:Eu2+, SrAl2O4:Eu2+,...) elemental analysis with EDX was readily correlated with the CL emission mappings. In all cases, the CL emission was also observed with a conventional CL setup using a CCD to check the validity of the CL mapping with the EDX detector.In conclusion, we explained and simulated why an EDX detector can be used for panchromatic CL mappings. The main advantage is that no additional software or hardware is required to obtain the mappings. Furthermore, this method allows mapping of the CL on samples with strong and inhomogeneous electric charging as a repeated, fast scanning of the sample surface can be used.
