The result showed that the luminous flux for LW white LED radiation power output is 298.7 lm and the total photons are 2.7×1018. If under ideal conditions, one electron-hole pair injected yields one blue photon and the quantum efficiency of the phosphor equals one, the numbers of electron-hole pair must equal to the numbers of white photons.

Mn-complexes in which Mn atom ligand with the N atom within ligand can stimulate the recovery of electron transfer and oxygen evolution. The trinuclear Mn-complex is extremely sensitive to the addition of CaCl2. It is suggested that there is an interaction between Ca2 and carboxyl within the trinuclear Mn-complex during photoactivation and this interaction benefits the ligation of Mn atom to the apo-WOC and form an active WOC. Binuclear MnMn complex shows slightly higher efficiency than binuclear MnMn complex in restoration of O2 evolution activity. It is suggested from our results that recovery of electron transport and O2 evolution with synthetic Mn-complexes is affected by different factors. Cl- can stimulate the reconstitution of WOC at the concentration of over 100mM;the maximal recovery of O2 evolution activity requires the presence of CaCl2 and 33 kDa protein polypeptide together. Bicarbonate can stimulate the reconstitution of WOC.

锰配合物中锰原子与配体中的氮原子配位连接时，能显著恢复电子传递活性和放氧活性；三核锰化合物在重组时对CaCl2的存在非常敏感，我们认为Ca2 与三核锰化合物中的羧基之间存在一定的相互作用，而这种作用有助于锰原子的光配位进而使三核锰化合物易于组装成有活性的水氧化复合物：双核锰化合物MnMn比双核锰化合物MnMn在恢复放氧活性方面更有效；影响锰化合物电子传递能力恢复的因素与影响锰化合物放氧活性恢复的因素不同；在锰蔟重组过程中，氯离子的浓度必须在100mM以上，才能有效进行光重组；最大光重组效率的获得必须有钙离子和33kDa多肽同时存在；碳酸氢根离子促进锰化合物与去锰光系统II的光组装。
