Fig. 5

a The emission spectra of operating devices by covering the different pressure-treated samples on a 365 nm near-UV chip, inset: photograph of operating white and yellow pc-LEDs. b The CIE chromaticity coordinates of the fabricated white and yellow pc-LEDs. c Heating-cooling cyclic stability of the white pc-LED in the range of 298-393 K. d PL spectra of the white pc-LED at different operating currents. e Integrated PL intensity of the white pc-LED as a function of aging times. The inset shows visual time-quenching behavior. f Photograph of three multicolor dolls under an operating white pc-LED. The device is operated at a voltage of 3.0 V (50 mA).
