Code and derived data for: Measured Host Optical Constants Shift Deep-Blue OLED Outcoupling by up to 14% While Leaving the Stack Design Intact

Fitted parameter sets, optical-constant tables, model outputs and scripts. Raw ellipsometry files are in the ellipsometry record. Methods: Scripts are written in Python 3 (NumPy, SciPy, pandas, matplotlib; RDKit for structure drawings where used). Each script reads the tables of this record or the raw files of the experiment records and writes numerical tables and figure panels (vector PDF with a 600-dpi PNG). Joint multi-angle, multi-spot spectroscopic ellipsometry fits with the substrate calibrated on bare Si (se_fit.py, se_lib.py), point-by-point (n,k) inversion and absorption-edge analysis (se_tables.py); optics-only outcoupling model of bottom-emitting OLED stacks (oc_lib.py, oc_runs.py); orientation descriptors of the calculated transition dipole moments.

Raw instrument files are in the experiment records of the series (AFM, UV-Vis, DRS, ellipsometry, PL, time-resolved PL, CV, DSC/TGA, XRD, FTIR, NMR/MS, electron microscopy, J-V, impedance, DFT).
