The present invention generally relates to composition and methods for downconverting light. In some embodiments, the composition and methods comprise an organic material, a nanocrystal, and a ligand capable of facilitating energy transfer between the organic material and the nanocrystal. In certain embodiments, the nanocrystal has a first excited energy state with an energy less than a triplet energy state of the organic material. The organic material, in some embodiments, may be aromatic and/or include one or more pi-conjugated carbon-carbon double bonds. In some cases, incident light may be absorbed by the organic material to produce two triplet excitons. The triplet excitons may then transfer to the nanocrystal via the ligand, where they can undergo recombination, resulting in the formation low energy photons.

Compositions and methods for the downconversion of light

A light emitting device can include a light source, a first electrode, a second electrode, a first barrier layer, a second barrier layer, and an emitter layer between the first barrier layer and the second barrier layer. A method of controllably generating light can comprise two states: An ON state, wherein an emitter layer of a device (which includes a photoluminescent pixel) is illuminated with a light source in the absence of an electric field, and the emitter layer generates light through photoluminescence; and an OFF state, wherein an emitter layer of a device (which includes a photoluminescent pixel) is illuminated with a light source in the presence of a static or time-varying electric field, and the electric field or induced current results in quenching of the emitter photoluminescence.

The disclosure provides methods and apparatus for release-assisted microcontact printing of MEMS. Specifically, the principles disclosed herein enable patterning diaphragms and conductive membranes on a substrate having articulations of desired shapes and sizes. Such diaphragms deflect under applied pressure or force (e.g., electrostatic, electromagnetic, acoustic, pneumatic, mechanical, etc.) generating a responsive signal. Alternatively, the diaphragm can be made to deflect in response to an external bias to measure the external bias/phenomenon. The disclosed principles enable transferring diaphragms and/or thin membranes without rupturing.
