By controlling the device design through the study of the emission of DDMA-TXO2 and DPO-TXO2, the behaviour of POZ-DBPHZ in a device with more than one emitter, and the combination of the three materials, respectively, we show that external quantum efficiencies as high as 16% can be obtained for a structure with a correlated colour temperature close to warm white, together with colour rendering index close to 80. However it is in their performance stability that provides the true breakthrough: at 1000 cd/m2 the efficiencies were still above 10%, which is one of the best for this type of devices. © 2017 The Author(s).}, funding_details={Japan Prize FoundationJapan Prize Foundation}, funding_details={Engineering and Physical Sciences Research CouncilEngineering and Physical Sciences Research Council, EPSRC, EP/L02621X/1, EP/K016164/1}, funding_details={DF 70040-020, 12027/13-8}, funding_details={Japan Society for the Promotion of ScienceJapan Society for the Promotion of Science, JSPS, JP15H00997}, funding_details={Ministry of Education, Culture, Sports, Science and TechnologyMinistry of Education, Culture, Sports, Science and Technology, MEXT}, funding_details={European CommissionEuropean Commission, EC}, funding_details={Ministry of Education, Culture, Sports, Science and TechnologyMinistry of Education, Culture, Sports, Science and Technology, MEXT}, funding_details={659288}, funding_details={Horizon 2020 Framework ProgrammeHorizon 2020 Framework Programme, H2020, 674990}, funding_text 1={The authors would like to acknowledge the EXCILIGHT project funded by the European Union's Horizon 2020 Research and Innovation Programme under grant agreement No. 674990 and EPSRC grant EP/K016164/1.
