Microwave photochemistry IV: Preparation of the electrodeless discharge lamps for photochemical applications

The electrodeless discharge lamps (EDLs) have been found to be suitable sources of UV/vis light for photochemical reactions. The EDL usually consists of a glass tube (quartz or Pyrex) filled under a reduced pressure with argon and an excitable substance (e.g. Hg, HgI2, Cd, I2, KI, P, Se, S), and generates UV/vis radiation when placed into the microwave field. The utilization of other filling material than mercury is practical and environmentally safe in the EDL performance. The original equipment for easy preparation of EDLs has been described in detail.
