Portable Analytical Detection Systems Based on Light Emitting Devices

Portable analytical detection systems based on light emitting devices, organic light-emitting diode (OLED), and electrogenerated chemiluminescence (ECL) are described. The OLED is composed of an Eu(III) complex, whose emission spectrum is very sharp, was applied for fluorescence detection, and ECL of a boron-dipyrromethene derivative showing relatively sharp spectrum was used for the absorbance measurements.
