Abstract:
Organic light emitting devices includes a light emission region between a cathode and anode. The light emission region comprises an organic light emitting material. The organic light emitting devices are formed by annealing as-fabricated devices. The annealing improves the performance of the as-fabricated devices, by decreasing their operating voltage and increasing their energy conversion efficiency. Multiple organic light emitting devices can be annealed to make the properties of the devices more uniform relative to each other.
Abstract:
An organic light emitting device containing (i) an anode or a first electrode; (ii) a hole transport layer containing, for example, a mixture of a porphyrin and a hole transport material (iii) a mixed region containing a mixture of (1) a hole transport material, and (2) an electron transport material; (iv) a cathode or second electrode, and wherein the organic light emitting device may further contain at least one of (v) an electron transport region interposed between the mixed region and the cathode; and (vi) a thermal protective element coated on one of the anode and cathode.
Abstract:
An organic light emitting device composed of: a first electrode; a second electrode; and a luminescent region including an organic electroluminescent material between the first electrode and the second electrode, wherein one of the first electrode and the second electrode includes both a substantially transparent charge injecting layer adjacent to the luminescent region and an electrically conductive light absorbing layer.
Abstract:
A toner process including, for example, mixing a latex with a colorant wherein the latex contains resin and an ionic surfactant, and the colorant contains a surfactant and a colorant; adding a polyaluminum chloride; affecting aggregation by heating; adding a chelating component and a base wherein the base increases the pH of the formed aggregates; heating the resulting mixture to accomplish coalescence; and isolating the toner.
Abstract:
