摘要:
The present invention is directed to systems and methods for producing an improved PSD scintillator by including a cross-linking agent, such as BPA-DM, in the polymer from which the scintillator is machined, and to PSD scintillators produced thereby. The cross-linking agent could also be used for plastic scintillators with significant incorporation of specialized dopants (boron, lead or bismuth) for thermal neutron or gamma radiation detection.

The present invention is directed to systems and methods for producing an improved pulse shape discriminating (PSD) scintillator by including a cross-linking agent, such as BPA-DM, in the polymer from which the scintillator is machined, and to PSD scintillators produced thereby. The cross-linking agent could also be used for plastic scintillators with significant incorporation of specialized dopants (boron, lead or bismuth) for thermal neutron, fast neutron and/or gamma radiation detection.

Improved electron acceptor materials for organic photovoltaic (OPV) cells are provided. More specifically, electron acceptor materials for OPVs can include vinylimide, vinylthioimide, alkynylimide and/or alkynylthioimide moieties. Experimental work with members of this class of material has demonstrated record solar cell power conversion efficiency (3.36%) for non-fullerene acceptors.
摘要:
A self-assembly process for preparing luminescent organic-inorganic nanocomposite thin films is disclosed. A homogeneous solution in water and an organic solvent is obtained containing a soluble silicate, a silica coupling agent, a surfactant, and an organic material having a hole transport, electron transport, and/or emissive material moiety. The silica coupling agent is selected to chemically react with the organic material. A film of the homogeneous solution is deposited onto a substrate. Preferentially evaporating the organic solvent enriches the concentration of water and non-volatile solution components to promote micelle formation. Organic materials migrate into the hydrophobic portion of the forming micelles. Continued evaporation promotes self-assembly of the micelles into interfacially organized liquid crystalline mesophases. Reacting the organic material and silica coupling forms a nanostructure self-assembly. Luminescent ordered nanocomposite structures prepared by the process, and organic-inorganic HLED devices fabricated from the luminescent organic-inorganic nanocomposite structures are disclosed.

The invention is directed to oxidized charge transport materials having hole transport capability in organic light emitting device (OLEDs). A charge transport compound including more than two triarylamine groups, or including at least one triarylamine group and at least one fluorene group, is partly complexed with an oxidant, such as a Lewis acid, preferably present in an amount between 0.2 and 20 percent by weight. The resulting charge transport materials exhibit good hole transport characteristics and film forming properties.
