1. Red Powderyttrium oxide: EuropiumY2O3:Eu3+, white powder, with a relative density of 5.05, belonging to cubic crystal system, work effectively under the excitation of253.7nm uv and cathode ray. It gives out orange-red fluorescence, with narrowband emission spectra at a main peak of 611nm. Thechromaticity coordinate x=0.651 , y=0.346, quantum efficiency of powder 84%, excited light reflectance 0.233, monochromaticfluorescent lamp efficiency 73.21m/W.

2.Green PowderMgAl11O19:Ce3+,Tb3+,chromaticity coordinate x=0.328,y=0.594.3. Blue PowderChlorine calcium borate: EuropiumCa2B5O9Cl: Eu2+ , white powder, with a relative density of 2.11, work effectively under the excitation of 253.7nm uv and cathode ray. Itgives out blue fluorescence. Wavelength of laser peak is 445 nm, half width 42 nm. Color coordinate x=0.147,y=0.041.Triphosphor Fluorescent Blend Powder: different color temperaturesRed, green and blue fluorescent powder are mixed together by a certain percentage to make different color temperature blend fluorescentpowder. Trichromatic phosphors, which are generally formulated by color temperatures 2700K, 2900K, 3200K, 5000K, 6400K asfluorescents' requires. Current trichromatic phosphors mainly refer to the phosphors which giving out red, green and blue fluorescentgenerated by rare earth ions. They compose differate fluorescent systems, mainly including: Aluminate system consisting of yttrium oxidered powder, aluminate green powder and blue powder; Phosphate system composed of yttrium oxide red powder, phosphate green powderand blue powder; Borate system made up from yttrium oxide red powder, borate green powder and blue powder; And many other mixedsystems.The blend powder system is made into slurry, coating the inner wall of low-voltage fluorescent lamp to make a trichromatic fluorescentlamp. It has different characteristics compared to general fluorescent lamp, such as: high brightness, efficiency 90—100 lm/W, wide rangeof color temperature, higher color rendering index Ra 80 in general, slow luminous decay, long life and energy-saving.Trichromatic phosphors are widely used in compacted energy saving fluorescent lamps, because of its strong capability against highenergy 185nm uv and high heat stability of keeping high brightness around 120C.
