    Abstract: Aspects of the present disclosure generally relate to short-wave infrared (SWIR) materials, SWIR detectors, and methods of use. In an aspect, a SWIR detector is provided and includes a conductive layer disposed over a first portion of a substrate, the conductive layer having a trench therein, and a hole transport layer disposed over at least a second portion of the substrate and within the trench of the conductive layer. The SWIR detector further includes a light conversion layer disposed over at least a portion of the hole transport layer, the light conversion layer comprising a composition having the formula AaBbMcXd, wherein: A is an organic group or ion thereof; B is an organic group, an inorganic group, or ion thereof; M is a metal or ion thereof; X is a halogen or ion thereof; and a, b, c, and d are numbers expressing amounts of A, B, M, and X.

    Abstract: Apparatus for controllably admitting a sample volume of engine exhaust into a bifurcated, closed-loop opacity chamber and wherein the exhaust sample is controllably directed away from the internal optics via symmetric flow inducing air guides. A pulsed light source is controllably directed through the opacity chamber and exhaust sample and the detected light is compared to a reference level so as to determine a relative measure of the sample's opacity. Attendant control circuitry permits the selected display of corresponding sample opacity and density values.

    Abstract: An automatic chemical analyzer for the analysis of physiological samples. A scanning monochromatic spectrophotometer may be used to determine the absorbance of the sample under control of a central processing unit. Outputs from one of several ion selective electrodes may also be selected by the system. The information obtained from the measurements is stored in memory or ouputted to output devices. Information about the test parameters may be read from an optical bar code associated with the test kit for the particular chemical analysis.

    Abstract: Techniques for detecting narcotics such as tetrahydrocannabinol (THC) or other aerosols such as cannabinoids, opioids, etc., in an exhaled breath using infrared spectroscopy are provided. An example of an apparatus for sensing THC according to the disclosure includes a tunable laser source, at least one photodetector, a sample cell disposed between the tunable laser source and the at least one photodetector, and at least one processor operably coupled to the tunable laser source and the at least one photodetector and configured to provide a control signal to the tunable laser source, determine a spectral absorption line or group of absorption lines associated with THC based on an intensity of infrared light detected by the at least one photodetector, and determine a THC concentration value based on the spectral absorption line intensity. A laser-based apparatus for sensing narcotics in exhaled breath may include a single, dual, or multi-optical frequency comb spectrometer.
