Applying Raman & PL Microscopy to Materials Characterisation - Webinar

Discover more from Edinburgh Instruments: www.edinst.com In this webinar, we explore how both techniques can be applied to the characterisation of different materials classes using the RMS1000 Confocal Raman & PL Microscope. Topics covered will include the Raman imaging of 2D nanomaterials such as graphene and TMDC monolayers, layer composition analysis in multilayer materials, and the spectral & lifetime PL imaging of semiconductors. 0:00 Introduction 1:52 Outline 3:50 Layout of a Confocal Microscope 7:44 Edinburgh Instruments RM5 & RMS1000 8:49 Raman Spectroscopy of Graphene 10:28 Graphene Defects 11:12 Mapping of Graphene Defect Density 12:52 Mono vs Multi-Layer Graphene 14:38 TMD Monolayers 19:07 Photoluminescence of Mos 21:27 Surface Coverage & Quality of TMDC Films 23:02 Multilayer Samples & Depth Profiling 24:08 The Challenge 24:58 Role of the Confocal Pinhole 27:21 Pinhole Size 29:27 Example: PET-PVC-PET Polymer Stack 32:16 What are Perovskites? 32:47 Hybrid Perovskite Solar Cells 33:36 PL of Solar Cells 34:57 CNT Hole Extraction Layer 37:16 PL Intensity Mapping 39:45 PL Lifetime Mapping: TCSPC
