Research Fellow

National University of Singapore

Dr. Nur Fadilah Jamaludin received her PhD from Nanyang Technological University (NTU) in 2020 on the “Modulation of Non-radiative Recombination in Organic-inorganic Halide Perovskites for Light Emission,” under the co-supervision of Professor Subodh Mhaisalkar and Associate Professor Cesare Soci. To date, she has more than 7 years of research experience and more than 25 publications on halide perovskite semiconductor materials for various optoelectronic applications including photovoltaics, light emitting diodes and neuromorphic devices. Currently a Research Fellow in Professor Silvija Gradečak’s group at the National University of Singapore (NUS), she is involved in the research of novel, technologically relevant two-dimensional (2D) materials for future electronics.

White Electroluminescence from Perovskite–Organic Heterojunction

Despite extensive reports on red and green perovskite-based LEDs (PeLEDs), development of white PeLEDs remains limited by the low photoluminescence quantum yield of white-emitting perovskites and the undesired energy-transfer (ET) process occurring in multidomain Ruddlesden–Popper perovskites. While ET is beneficial for achieving efficient monochromatic emissions, the broadband spectrum required for white electroluminescence makes this phenomenon undesirable. Processing-induced physical separation of emitters has been proposed as an effective way to curb ET. Here, it is shown that by adopting a bilayered emitter configuration, achieved through a facile antisolvent-assisted spin-coating process, an increase in spatial separation between the blue perovskite and red emitting organic species employed can be realized, leading to a record efficiency of 1.3%, the highest from a perovskite-based white electroluminescent device at the time of publication.
