(a) Molecular structures of host and guest molecules used as emitting layers in a general device structure (Tables S13). Three studies were conducted: (b) one with green and blue emitters with thickness (x) of the green’s Host-Guest system between 10 and 20 nm, (c) another with orange (concentrations – y – of 5, 8 and 11%) and blue. The best results were merged into the final device structure (d) and thicknesses of DPEPO (z) were varied between 7 and 15 nm.
