摘要： A method for producing quantum dots. The method includes cleaning an oxide substrate and separately cleaning a metal source. The substrate is then heated and exposed to the source in an oxygen environment. This causes metal oxide quantum dots to form on the surface of the substrate.

摘要： The invention encompasses photoacoustic apparatuses and photoacoustic spectrometry methods. The invention also encompasses sample cells for photoacoustic spectrometry, and sample cell/transducer constructions. In one aspect, the invention encompasses a photoacoustic spectroscopy apparatus, comprising: a) a sample reservoir and an acoustically-stimulable transducer acoustically coupled with the sample reservoir, the transducer comprising a detector surface having a substantially planar portion; and b) a beam of light configured to be directed through the sample at an angle oblique relative to the substantially planar portion of the detector surface to generate sound waves in the sample. In another aspect, the invention encompasses a photoacoustic spectroscopy sample cell, comprising: a) a first block of material having opposing front and back surfaces, the front surface comprising a substantially planar portion configured to be against a sample and the back surface comprising a substantially planar portion configured to be joined to a transducer, the back surface being parallel to the front surface; and b) a pair of opposing side surfaces joined to opposite ends of the front and back surfaces, one of the opposing side surfaces being configured for passage of light therethrough and extending at a first oblique angle relative to a plane containing the substantially planar portion of the front surface.
