Answer:

Rare earth phosphors are mainly used in office, store and factory high performance fluorescent lamps. Since the middle of 80s, with the development of less expensive fluorescent phosphor containing terbium, the application of this energy-saving lamp has been increasing rapidly. In mid 90s, the international launch of the TMT2 straight tube fluorescent lamp, the diameter of only 7mm, power is 6W~13W, light efficiency is 621m/W.T5 straight tube type fluorescent tube diameter is 16mm, power 14W~35W, 28W fluorescent light up to 104m/W, life is more than 16000h. in new development of high power light type 55W~120W is suitable for outdoor lighting compact energy saving rare earth fluorescent lamp, light efficiency more than 801m/W.
When the lamp is energized, the tungsten electrode is discharged between the two ends of the lamp. Light emitting from short wave radiation into visible light mainly by phosphor. Rare earth three primary fluorescent lamps, which contain yttrium, europium and terbium rare earth phosphors, emit brighter light and are closer to the solar spectrum than standard fluorescent lamps. At the same time, the light can save 50% energy consumption, and the three primary color phosphor powder is mixed by three kinds of phosphor powder of three narrow band red emitting (611nm), green (545nm) and blue (450nm) color spectrum.
Three color phosphor (by fluorescent powder red, green and blue three kinds of rare earth according to a certain proportion) energy-saving lamps made of incandescent lamp, because the light efficiency is higher than two times, light or attention all over the world. A typical hot cathode fluorescent lamp is coated with phosphor powder on the inner wall of a glass tube and emits visible light under ultraviolet excitation.
The luminescent materials with rare earth compounds as matrix and rare earth elements as activators are mostly in the latter category, namely rare earth phosphors. Rare earth elements are rich in electronic energy levels, because 4f orbitals exist in the electronic configurations of rare earth atoms, which create conditions for a variety of energy levels to achieve a wide range of luminescence properties.
Material luminescence can be divided into two categories: one is the material heating, thermal radiation and the light, the other is the object of excited energy absorption and the transition to the excited state (non steady state) in reverse to the ground state in the process of releasing energy in the form of light.
