borophosphate 眼镜的作文上的白光的颜色点的依赖与铕(Eu ) 和铽(Tb ) 共同做以稀土元素离子的原子价变化被调查了。在下面紫外(紫外)刺激,白光被观察从在为Eu2+的 425 nm 的 4f65d 4f7 乐队转变排放的联合, 5D0 7F J ( J=1 , 2 )在 593 nm 的线排放和为Eu3+的 611 nm ,并且在为Tb3+的 545 nm 的 5D4 7F5 乐队转变排放。由改变玻璃作文,结果的排放颜色能高效地被调节。最后,有委员会的优化的白光国际 de IEclairage (CIE ) 坐标(0.3382, 0.2763 ) 并且在 5010 K 的相互关联颜色温度(CCT ) 被完成。
The dependence of color points of white light on the composition of bomphosphate glasses co-doped with europium (En) and terbium (Tb) has been investigated in terms of valence change of rare earth ions. Under ultraviolet (UV) excitation, the white light is observed to be from a combination of 4f65d → 4f7 band transition emission at 425 nm for Eu^2+, 5D0 → ^7Fj (J= 1, 2) lineemissions at 593 nm and 611 nm for Eu^3+, and 5D4 → 7F5 band transition emission at 545 nm for Tb^3+. By varying the glass composition, the resultant emission color can be tuned efficiently. Eventually, the optimized white light with commission international de I'Eclairage (CIE) coordinate of (0.3382. 0.2763) and the correlate color temperature (CCT) at 5010 K are achieved.
