“…A chemical sensor is commonly defined as a device that, as the result of its chemical interaction with an analyte, transforms either qualitative or quantitative chemical information into an analytically useful signal [1]. A sensor was also defined as a molecule (or nanoparticle) acting as a reporter moiety that communicates the presence of an analyte via modulation of an analytical signal [2,3]. Strictly speaking, a chemical sensor is a miniaturized device capable of providing continuous real-time and on-line information about the presence of specific analyte(s) in a sample [4,5].…”

The development of chemical sensors for environmental analysis based on fluorescence, phosphorescence and chemiluminescence signals continues to be a dynamic topic within the sensor field. This review covers the fundamentals of this type of sensors, and an update on recent works devoted to quantifying organic pollutants in environmental waters, focusing on advances since about 2005. Among the wide variety of these contaminants, special attention has been paid polycyclic aromatic hydrocarbons, pesticides, explosives and emerging organic pollutants. The potential of coupling optical sensors with multivariate calibration methods in order to improve the selectivity is also discussed.

“…PL measurements of the samples show tunable visible emission features that can be partly related to the combination of ZnO nano particles and nano wires. Such a promising fluorescent materials are very attractive for a variety of applications such as synchronous fluorescent sensing, DNA sequencing, bioprocess monitoring etc., and it may be expected that such tunable multiwavelength nanocrystals can be developed in the future by more accurate measurement [26]- [28].…”

This letter reports ZnO nano nanocrystals with tunable visible fluorescent emission which utilizes optically stimulated luminescence (OSL). ZnO nano nanocrystals deposited on glass substrates, and the blue-shifted two narrow photoluminescence peaks at the violet band and green band have been observed for the first time. Such promising multiwavelength tunable nanocrystals can be easily fabricated and are very attractive for a variety of applications such as synchronous fluorescent sensing, DNA sequencing, bioprocess monitoring, etc.

“…Luminol (3-aminophthalhydrazide), as one of the most widely used luminescence probes, has stirred particular interest in view of exciting applications in the fields of chemiluminescence (CL) and fluorescence [20,21]. Although chromatographic separation of Ln III with luminol-H 2 O 2 system CL detection has been reported [22,23], the subtle changes of the luminescence behavior for the lanthanide family have not been described and interaction parameters of Ln III with luminol have not been given by CL with flow injection (FI) analysis.…”
