"In this work, the tuning from blue or white emission from a single emitting layer OLED is reported. The tuning was through different exciplex states in devices whit the following architecture ITO / PEDOT: PSS / CZDD / BPhen / Ca-Ag. For the mentioned architecture, the absence of electron transport layer (ETL) BPhen generate a blue emission. In this architecture without BPhen by decreasing the thickness of PEDOT: PSS several blue tonalities were achieved, the wavelength of maximum emission ran from 430 to 550 nm and CIE coordinates changed from (0.20, 0.22) to (0.26, 0.45). For the architecture with ETL white emission was observed due to the exciplexes states induced at CZDD/BPhen interface, emitting at longer wavelengths giving the complementary emission for white light. For this architecture the changing of PEDOT:PSS let us the tuning of the emission from cold to warm white: the luminous efficacy and current efficiency for blue emission were of 5.2 lm/W and 6 meanwhile for white emission were 6.8 lm/W and 9, respectively."
