Abstract: A method includes exposing a non-aqueous solution to ultraviolet illumination, where the non-aqueous solution includes one or more lanthanide elements and one or more photo-initiators. The method also includes producing lanthanide nanoparticles using the non-aqueous solution. The non-aqueous solution could be formed by mixing a first non-aqueous solution including the one or more lanthanide elements and a second non-aqueous solution including the one or more photo-initiators. The non-aqueous solution could include one or more metallic salts, where each metallic salt includes at least one lanthanide element. The one or more metallic salts could include erbium chloride, and the one or more photo-initiators could include benzophenone. The non-aqueous solution could include an organic solvent, such as an alcohol.

Abstract: An apparatus and method of calibrating a sensor. A voltage is applied to a first carbon nanotube layer to obtain a first temperature of the first carbon nanotube layer. A thermally conductive layer is used to provide a substantially uniform temperature related to the first temperature of the first carbon nanotube layer by smoothing a spatial variation of the first temperature. A second carbon nanotube layer receives the substantially uniform temperature and emits a first blackbody radiation spectrum to calibrate the sensor. The apparatus may be used to emit a second black body radiation spectrum by altering the applied voltage.

Abstract: A thin-film device for generating a blackbody spectrum is disclosed. The device includes first layer configured to generate heat in response to an applied voltage and a second layer configured to generate the blackbody radiation spectrum in response to the heat from the first layer. A thermocouple is disposed between the first layer and the second layer for measuring a temperature at the second layer. The thermocouple measures temperature at the second layer in order to control temperature at the second layer. The thermocouple can be a copper-carbon nanotube thermocouple.

Abstract: A light source, calibration device and method of calibrating an imaging device is disclose. The calibration device includes the light source which includes an ultraviolet light layer that, in operation, generates ultraviolet light, and a quantum dot layer that absorbs the ultraviolet light and, in response, generates radiation within the near infrared region at a selected intensity. The near infrared light is received at the selected intensity at the imaging device and a sensitivity of the imaging device is altered to detect the near infrared light at the selected intensity provided by the light source.

Abstract: An apparatus includes a substrate having a recess and a first insulator submerged in the recess of the substrate. The apparatus also includes a cover having a second insulator that, together with the first insulator, defines an insulated volume. The apparatus further includes one or more components to be cooled located over the first insulator and within the insulated volume. The apparatus could also include one or more electrical conductors located over the first insulator, where at least one of the one or more components is electrically connected to the one or more electrical conductors. The one or more electrical conductors could be submerged in the recess of the substrate. The one or more electrical conductors could be thermally-insulative at cryogenic temperatures and could include carbon nanotubes. The first and second insulators could include foam or aerogel insulation.
