The study of intramolecular decay and intermolecular energy transfer for phosphorescent organic light-emitting devices

Compared to the PtOO7-based system, the greater EQE of the PtON7-based system is mainly governed by the stronger energy transfer efficiency (ηEET); thus, it is necessary to evaluate ηEET from hosts to guests for the rational design of OLEDs.

En este trabajo reportamos el uso de la espectroscopia de retrodispersión de Rutherford (RBS) para el análisis, búsqueda de contaminantes y medición del espesor de película delgadas de organo-lantánido [SmxEuy(TTA)3(TPPO)2] utilizadas como capas emisoras de luz en diodos orgánicos emisores de luz (OLEDs).También se hace un estudio de fotoluminiscencia de las películas de [SmxEuy(TTA)3(TPPO)2], y se encuentra que la emisión de luz de la mezcla se realiza independientemente por las moléculas [Sm(TTA)3(TPPO)2] y [Eu(TTA)3(TPPO)2], no observándose una transferencia intermolecular de energía entre dichas moléculas. Palabras clave.-Samario, Europio, Fotoluminescencia, RBS, OLED. ABSTRACTIn this work we report the use of Rutherford backscattering spectroscopy (RBS) for the analysis, search of contaminants and measurements of thickness of the organic-lanthanide [SmxEuy(TTA)3(TPPO)2] thin films used as light-emitting layer in organic light-emitting diodes (OLEDs). Also a study of photoluminescence of the films [SmxEuy(TTA)3(TPPO)2] is realized, and it is found that the emission of light of the mixture is carried out independently for the molecules [Sm(TTA)3(TPPO)2] and [Eu(TTA)3(TPPO)2], not being observed a intermolecular energy transfer between these molecules.
