Mechanism of Emission
A cold cathode fluorescent lamp is the fluorescent lamp which is operated in the range of normal glow discharge. Rare gas and a small mount of mercury (a few mg) are filled in the glass tube coated with phosphor (fluorescent material). By adding high electric field (high frequency) between electrodes at both ends of the glass tube, glow discharge occurs in the low pressure mercury vapor. Mercury atoms which are excited by its discharge, emit ultraviolet (253.7nm), and these ultraviolet rays excite the phosphor. When the excited atoms of phosphor return to low energy level, the visible light is emitted. (Its wave length is decided by the phosphor material.)
