Narrow Emission

We report 10 and 20μm spectroscopic observations of four C–rich post–AGB objects which exhibit the unidentified emission feature at 21μm. The observations were carried out in October 1990 and May 1991 using CGS3 on UKIRT. The spectral resolutions were 70 for the wavelength range of 7.4–13.3μm and 80 for the region between 15.4–24.1μm. Three of the sources reported here are from the list of Kwok, Volk & Hrivnak (1989), i.e., IRAS 04296+3429; IRAS 07134+1005 and IRAS 22272+5435. Figure 1 shows the full spectrum of IRAS 04296+3429 and IRAS 22272+5435. The 10μm spectra of these objects exhibit UIR bands whose peaks all fall longwards of the usual peak wavelengths associated with such features. This may be related to the fact that they are the lowest excitation objects so far found to exhibit UIR emission bands. We also found narrow emission features superimposed on the long wavelength wing of the 21μm emission bands of IRAS 04296+3429 and IRAS 22272+5435. The fourth object we observed, SAO 163075, was found to also exhibit a (weak) 21μm emission feature. However, there is no PAH features in the 10μm region, apart from the plateau at 12μm.

Narrow Emission

The blue light-emitting material was synthesized. With the non-doped, blue-emitting material in the multilayer device structure, it was possible to achieve the luminous efficiency of 3.38 cd/A at 110 mA/cm2. The EL spectrum of the ITO / CuPc / NPB / BDPSP / Alq 3/ Mg : Ag device showed a narrow emission band with full width at half maximum (FWHM) 70 nm and λ max =448.25 nm . The emitting color of the device showed the highly pure blue emission (x,y)=(0.158, 0.10) for ITO / CuPc / NPB / BDPSP / Alq 3/ Mg : Ag in CIE (Commission Internationale de l'Eclairage) chromaticity coordinates.

Tunable Emission

Inorganic perovskite CsPbBr3−xIx(x= 0–3) QDs with tunable emission wavelength, narrow emission band and high quantum yields were synthesized. The fabricated CsPbBrI2QD-modified WLEDs show excellent performance in luminous efficacy, CCT and CRI, which are quite stable at an operational current as high as 350 mA.
