The power plant combusts a hydrocarbon fuel with oxygen to produce high temperature high pressure products of combustion. These products of combustion are routed through an expander to generate power. The products of combustion are substantially free of oxides of nitrogen because the oxidizer is oxygen rather than air. To achieve fast starting, oxygen, fuel and water diluent are preferably stored in quantities sufficient to allow the power plant to operate from these stored consumables. The fuel can be a gaseous or liquid fuel. The oxygen is preferably stored as liquid and routed through a vaporizer before combustion in a gas generator along with the hydrocarbon fuel. In one embodiment, the vaporizer gasifies the oxygen by absorption of heat from air before the air is routed into a separate heat engine, such as a gas turbine. The gas turbine thus operates on cooled air and has its power output increased.

Optoelectronic devices and methods for their fabrication having enhanced and controllable rates of the radiative relaxation of triplet light emitters are provided exemplified by organic light emitting devices based on phosphorescent materials with enhanced emission properties. Acceleration of the radiative processes is achieved by the interaction of the light emitting species with surface plasmon resonances in the vicinity of metal surfaces. Non-radiative Förster-type processes are efficiently suppressed by introducing a transparent dielectric or molecular layer between the metal surface and the chromophore. For materials with low emission oscillator strengths (such as triplet emitters), the optimal separation distance from the metal surface is determined, thus suppressing energy transfer and achieving a significant acceleration of the emission rate.

Si-doped porous GaN is fabricated by UV-enhanced Pt-assisted electrochemical etching and together with a low-temperature grown buffer layer are utilized as the template for InGaN growth. The porous network in GaN shows nanostructures formed on the surface. Subsequent growth of InGaN shows that it is relaxed on these nanostructures as the area on which the growth takes place is very small. The strain relaxation favors higher indium incorporation. Besides, this porous network creates a relatively rough surface of GaN to modify the surface energy which can enhance the nucleation of impinging indium atoms thereby increasing indium incorporation. It shifts the luminescence from 445 nm for a conventionally grown InGaN structure to 575 nm and enhances the intensity by more than two-fold for the growth technique in the present invention under the same growth conditions. There is also a spectral broadening of the output extending from 480 nm to 720 nm.
