other luminescent organisms in the environment have been found, CL has aroused considerable interest for deeper research and application [2]. Definitely, CL analysis has excellent advantages including high sensitivity, low background interference, highly responsive signals, safe operation process and portable equipment [3], which has been applied to detection towards the concentration of catalyst, reactant, CL inhibitor and enhancer [4] Among numerous branches of CL systems, acting as a classic and interesting strategy, gas-solid phase CL has recently been a rapidly growing area. Such CL evolves in infrared, visible, and even in ultraviolet regions through chemical reactions between gas and solid reactants on the surface of solid matter. It acts as an indicator and monitor of gas-solid phase reactions to provide information during the process of reaction [10]. Moreover, this strategy also enables investigations of gas-solid phase reactions through sensitive and simple spectral method [11]. In addition, application of gas-solid phase CL has extended to gas-phase and solid-phase diagnose and detection due to its strong intensity of signals and unique property. Over decades of years of investigation and development, gas-solid phase CL has become an effective detection method in analytical chemistry. Recent progress mainly focuses on development of new gas-solid phase CL systems and their practical applications, while many interesting results have been reported. Obviously, the excellent sensitivity and intensity of gas-solid phase CL has made it a good candidate as a novel CL technology, which has revealed great potential for future analysis and test.Considering the aforementioned properties, gas-solid phase CL have received considerable attentions in different areas of Abstract Serving as a classic and interesting strategy, gassolid phase chemiluminescence (CL) has recently been a rapidly growing area where CL is emitted through chemical reactions between gas and solid reactants occurred on the surface of solid matter. This CL system provided a sensitive and simple spectral method for investigating gas-solid phase reactions while information on the rate constants, intermediate productions, surface states and reaction mechanisms of interaction could be acquired. Recent progresses mainly concentrate on development of new gas-solid phase CL systems and their practical applications. This review paper summarized main classifications, mechanisms and applications of gas-solid phase CL. The future prospects for gas-solid phase CL are discussed.

“…Some materials satisfy these requirements (e.g. SiC single crystals [9]), and some analyzed gases are not aggressive (compared to H or O atoms). However, most of the materials and their surfaces do undergo some modification in vacuum or active gas atmosphere due to chemical and/or physical etching.…”

Novel Chemical Sensor Concept for Neutral Radical Detection in Gas Phase

et al. 2005

View full text Add to dashboard Cite

A novel concept of solid-state chemical sensors for neutral radical detection in gas-phase and related technique are proposed based on chemiluminescence of sensing materials excited by heterogeneous chemical reactions of radicals on sensor surface. The radical species of interest include H, O, N, O 2 , CO, SO, NO and others. Surface activated phosphors, nano-phosphors and semiconductor films are good candidates for sensors. The advantages of these sensors are the enhanced sensitivity (~10 5 at/cm -3 or better), real-time response, reliability, proximate analysis, ability to be fabricated in combination with up-to-date nanotechnologies.
