“…Hence, the electrical detection of the analyte might occur either during the sorption or during the release period (Kubinski and Visser, 2008;Groß et al, 2013a). In the literature, this change in the accumulationlevel is detected mainly optically (Tanaka et al, 1999;Sasaki et al, 2001;Maruo, 2007) or gravimetrically (Matsuguchi et al, 2005). Recently impedimetric approaches have emerged (Varghese et al, 2001;Mattoli et al, 2007;Helwig et al, 2008;Geupel et al, 2010;Hennemann et al, 2012a;Groß et al, 2012c).…”

“…2a increases in the presence of the analyte gas. Thereby, the slope of the time-dependent sensor response reflects the sorption rate and correlates with the actual analyte concentration c(t) (Dasgupta et al, 1998;Sasaki et al, 2001;Reyes et al, 2006;Groß et al, 2012a;Mukherjee et al, 2012). In the absence of the analyte, i.e., if c = 0 ppm, no signal recovery occurs, the sensor response remains constant and the response change due to the analyte is irreversible (Nieuwenhuizen and Harteveld, 1997).…”

Abstract. The aim of this article is to introduce the operation principles of conductometric solid-state dosimeter-type gas sensors, which have found increased attention in the past few years, and to give a literature overview on promising materials for this purpose. Contrary to common gas sensors, gas dosimeters are suitable for directly detecting the dose (also called amount or cumulated or integrated exposure of analyte gases) rather than the actual analyte concentration. Therefore, gas dosimeters are especially suited for low level applications with the main interest on mean values. The applied materials are able to change their electrical properties by selective accumulation of analyte molecules in the sensitive layer. The accumulating or dosimeter-type sensing principle is a promising method for reliable, fast, and long-term detection of low analyte levels. In contrast to common gas sensors, few devices relying on the accumulation principle are described in the literature. Most of the dosimeter-type devices are optical, mass sensitive (quartz microbalance/QMB, surface acoustic wave/SAW), or field-effect transistors. The prevalent focus of this article is, however, on solid-state gas dosimeters that allow a direct readout by measuring the conductance or the impedance, which are both based on materials that change (selectively in ideal materials) their conductivity or dielectric properties with gas loading. This overview also includes different operation modes for the accumulative sensing principle and its unique features.

“…The optical response of the perylene/PMMA sensor films to NO 2 was previously measured under controlled conditions using premixed gas concentrations of NO 2 in nitrogen gas (Matheson) (9).

An optical sensor system has been developed for the autonomous monitoring of NO 2 evolution in energetic material aging studies. The system is minimally invasive, requiring only the presence of a small sensor film within the aging chamber. The sensor material is a perylene/PMMA film that is excited by a blue LED light source and the fluorescence detected with a CCD spectrometer. Detection of NO 2 gas is done remotely through the glass window of the aging chamber. Irreversible reaction of NO 2 with perylene, producing the non-fluorescent nitroperylene, provides the optical sensing scheme. The rate of fluorescence intensity loss over time can be modeled using a numerical solution to the coupled diffusion and a nonlinear 4 chemical reaction problem to evaluate NO 2 concentration levels. The light source, spectrometer, spectral acquision, and data processing were controlled through a Labview program run by a laptop PC. Due to the long times involved with materials aging studies the system was designed to turn on, warm up, acquire data, power itself off, then recycle at a specific time interval. This allowed the monitoring of aging HE material over the period of several weeks with minimal power consumption and stable LED light output. Despite inherent problems with gas leakage of the aging chamber we were able to test the sensor system in the field under an accelerated aging study of rocket propellant. We found that the propellant evolved NO 2 at a rate that yielded a concentration of between 10 and 100 ppm. The sensor system further revealed that the propellant, over an aging period of 25 days, evolves NO 2 with cyclic behavior between active and dormant periods.5

The invention of lasers, which took place a few decades ago, marks a milestone in the past, present, and future technologies in optoelectronics. In particular, the colorful and white tones produced by lasers are appealing from a utilization standpoint and align well with human eye perception. In this paper, an idea for a white laser based on the attractive perylene family of luminescent dyes is introduced. This concept provides multicolor emission and brilliant photostability upon external optical pumping. The main advantage of the approach is the construction of a fully organic and two‐component white laser. The versatility of the system is demonstrated by assembling multicolor, tunable, and efficient fluorescent systems using a liquid crystalline matrix, which is supported by comprehensive experimental studies. Additionally, by utilizing laser spectroscopy techniques, it is able to narrow the emission bandwidth and enhance the light in a typical synthetic polymeric matrix. This leads to the realization of white lasing emission with just two luminescent dyes: perylene blue and perylene orange.
