Fluorescent lamp trichromatic

Cerium magnesium aluminate is a highly efficient green phosphor (lmax. = 541 nm), which is used in trichromatic fluorescent lamps. The high quantum yield of 65 % is effected by the energy transfer from the sensitizer, Ce3 +, to the activator, Tb3 +. ... 

The phosphor LaP04 Ce3+, Tb3+ has assumed importance as the green component in trichromatic fluorescent lamps. The emission maximum is at 544 nm and the... 

Sr3(P04)2 SrCl2 Eu2+ can be excited by radiation from the entire UV range. The excitation maximum lies at 375 nm and the emission maximum at 447 nm. Upon successive substitution of Sr2+ by Ca2+ and Ba2 +, the emission maximum shifts to 450 nm. In the preparation, SrCl2 is used in excess to improve the crystallization [5.378], The phosphor was used as the blue component in trichromatic fluorescent lamps [5.379] and in the first generation of compact lamps. 

The red television phosphor is based on europium. This phosphor is also used in trichromatic fluorescent lamps where a blend of red, blue and green phosphors gives white light.
