Development of Rh6G thin film as fluorescence sensor for explosive vapor detection Mingyu Chapman Abstract Self-organized rhodamine 6G (Rh6G) thin films on a glass substrate were prepared by spin-coating, dip-coating, and drop-coating. The thickness of the Rh6G layer strongly influences both.

      Galstyan et al. investigated the hydrogen sensor of Al-doped ZnO thin film, which have high sensitivity to low concentrations of hydrogen in air (1, ppm). Liu et al. have reported a great enhancement of the hydrogen sensing performance of ZnO thin films by Mg doping, and suggested that the higher sensitivity of Mg-doped ZnO thin films Cited by:   The sensor performance was tested with diluted NO2 in breathing air at concentrations ranging from to ppm. Under UV illumination, the TiO2 film shows an adequate and reversible response with relatively short response time (~ s) at room : Ting Xie, Nichole Sullivan, Kristen L.

    The paper considers SnO 2 and In 2 O 3 thin films as materials for the design of solid-state conductometric ozone sensors in depth. In particular, the present review covers the analysis of the fundamentals of SnO 2 - and In 2 O 3 -based conductometric ozone sensor operation. The main focus is on the description of mechanisms of ozone interaction with metal oxides, the influence of air humidity Cited by: Thin film heat flux gauges have the advantage of high frequency response and minimal flow disturbance. A thin film heat flux sensor developed at NASA GRC operates by measuring the temperature difference between thin film temperature sensors under different thicknesses of thermal insulating films, as shown in Figure 1 (Ref. 6). The sensor is File Size: 4MB.

Thin-film organic photodiodes for integrated on-chip chemiluminescence detection—Application to antioxidant capacity screening Article in Sensors and Actuators B Chemical (2) July.

A low noise optical sensor and biocompatible microscale optical filters for integrated fluorescence sensors were developed and tested. The sensor was fabricated in a mum CMOS process. The fabrication and performance of an ultra-thin-film integrated gas sensor for detecting impurities in semiconductor process gases are described.

The thermocouple design employs a cable distribution node (on the chamber side) that increases the accuracy of temperature readings to within +/- 1°C.

The Phoenix™ thin film sensor can automatically graph temperature and frequency alongside the corresponding rate and thickness values, allowing for real-time correction and accuracy up to Hz. The work described here concerns the fabrication of cost-effective biosensors that permit to amplify a fluorescence signal without a complex nano-structuration of the surface.

The idea is to put to profit the natural pseudo nano-structuring that is observed when depositing metallic layers by various micro-fabrication techniques. This new architecture consists of a glass substrate.
