FIG. 2.

Current-voltage-luminescence characteristics of blue light-emitting device with 6% TPF doped in DPF. Forward (0 to 13 V) and reverse (0 to ) bias scans are applied, whereas the current and electroluminescence are measured at the same time.

FIG. 3.

(a) PL spectra and (b) EL spectra of different TPF doping concentrations. The concentrations range from 0%, 1% to 6% TPF in DPF host and pure TPF. The PL spectra are measured with excitation at 300 nm. The EL spectra are measured while biasing at constant current of 3 mA.
