Abstract

A method of processing a composite material to tailor white light emission of the resulting composite during excitation. The composite material is irradiated with a predetermined power and for a predetermined time period to reduce the size of a plurality of nanocrystals and the number of a plurality of traps in the composite material. By this irradiation process, blue light contribution from the nanocrystals to the white light emission is intensified and red and green light contributions from the traps are decreased.

Final Report: Stable, High Efficiency White Electrophosphorescent Organic Light Emitting Devices (OLED) by Reduced Molecular Dissociation

Technical Report Forrest, Stephen R. ; Thompson, Mark E. ; Hack, Mike

Pursued new strategies for increasing the lifetime of blue phosphorescent light emitting devices (PHOLEDs) by: Seeking robust dopant &host molecular pairs whose energy gaps allowed both to participate in charge conduction in the PHOLED Emissive Layer (EML). While many molecules were explored, no dopant/host pairs were identified with performance exceeding initial best performers. Made performance gains by tailoring the dopant profile, (~500/1500 hour T ₇₀, 1000 nits) but were short of the 5000 hour goal. Introduced “excited state sinks” co-doped with the host & phosphor in the EML to reduce the lifetime of multiply-excited triplets and/or charge carriers such thatmore »« less

Novel rare earth ions-doped oxyfluoride nano-composite with efficient upconversion white-light emission

Journal Article Daqin, Chen ; Wang Yuansheng ; Yunlong, Yu ; ... - Journal of Solid State Chemistry

Transparent SiO{sub 2}-Al{sub 2}O{sub 3}-NaF-YF{sub 3} bulk nano-composites triply doped with Ho{sup 3+}, Tm{sup 3+} and Yb{sup 3+} were fabricated by melt-quenching and subsequent heating. X-ray diffraction and transmission electron microscopy measurements demonstrated the homogeneous precipitation of the {beta}-YF{sub 3} crystals with mean size of 20 nm among the glass matrix, and rare earth ions were found to partition into these nano-crystals. Under single 976 nm laser excitation, intense red, green and blue upconversion emissions were simultaneously observed owing to the successive energy transfer from Yb{sup 3+} to Ho{sup 3+} or Tm{sup 3+}. Various colors of luminescence, including bright perfectmore »« less

Strong blue and white photoluminescence emission of BaZrO{sub 3} undoped and lanthanide doped phosphor for light emitting diodes application

Journal Article Romero, V. H. ; De la Rosa, E., E-mail: elder@cio.mx ; Salas, P. ; ... - Journal of Solid State Chemistry

In this paper, we report the obtained strong broadband blue photoluminescence (PL) emission centered at 427 nm for undoped BaZrO{sub 3} observed after 266 nm excitation of submicron crystals prepared by hydrothermal/calcinations method. This emission is enhanced with the introduction of Tm{sup 3+} ions and is stronger than the characteristic PL blue emission of such lanthanide. The proposed mechanism of relaxation for host lattice emission is based on the presence of oxygen vacancies produced during the synthesis process and the charge compensation due to the difference in the electron valence between dopant and substituted ion in the host.

White light emitting Ho{sup 3+}-doped CdS nanocrystal ingrained glass nanocomposites

Journal Article Dey, Chirantan ; Karmakar, Basudeb ; Goswami, Madhumita - Applied Physics Letters

We report the generation of white light from Ho{sup 3+} ion doped CdS nanocrystal ingrained borosilicate glass nanocomposites prepared by the conventional melt-quench method. Near visible 405 nm diode laser excited white light emission is produced by tuning the blue emission from the Ho{sup 3+} ions, green band edge, and orange-red surface-state emissions of the nanocrystalline CdS, which are further controlled by the size of the nanocrystals. The absorption and emission spectra evidenced the excitation of Ho{sup 3+} ions by absorption of photons emitted by the CdS nanocrystals. The high color rendering index (CRI = 84–89) and befitting chromaticity coordinates (x = 0.308–0.309, y = 0.326–0.338) ofmore »« less
