Analytical Use of Easily Accessible Optoelectronic Devices: Colorimetric Approaches Focused on Oxygen Quantification
Rapid technological progress in digital color imaging devices, such as charge-coupled devices (CCD), complementary metal-oxide-semiconductor (CMOS) cameras, liquid crystal display (LCD), and digital light projection (DLP) devices, makes these optoelectronic products nearly ubiquitous in our daily lives. For example, relatively high-quality color images can be obtained anytime with mobile phone cameras and wireless webcams (some products as low as several tens of US dollars) and then be transmitted wirelessly. These color imaging devices were originally designed as "sensory" or "perceptual" devices that mimic the human eye when responding to visible wavelengths. This chapter introduces the potential use of these color imaging devices as economic analytical instruments. After we briefly review prospective luminophores amenable for colorimetric chemical quantification using color imaging devices, we will describe oxygen quantification as exemplary applications of this approach.
