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: A hyperspectral calibrator comprises a composite light source disposed within a housing and including an ultraviolet light emitting diode (UV LED) and a phosphor arranged such that a first beam generated by the UV LED is transmitted through the phosphor to produce and emit a calibration beam that is spectrally continuous over a wavelength range extending from 0.4 μm to 0.7 μm, the housing having an output opening and configured to direct the calibration beam emitted from the composite light source to the output opening to produce a calibration beam at the output opening.

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.
