Title :
Theoretical Study on Novel and Efficient Near-Infrared Multiphoton Quantum Splitting in 
Ion-Doped  that splits one ultraviolet-visible photon into NIR multiphotons can be developed for solar energy conversion. In this paper, we theoretically investigate the underlying mechanism of NIR QS in Ho<sup>3+</sup> single- and Ho<sup>3+</sup>-Yb<sup>3+</sup> dual-doped β-NaYF<sub>4</sub> by modeling and solving rate and power propagation equation system. The highest quantum efficiency is estimated to be 257% among studied systems. The total amount of output NIR photons may be increased to meet the purpose of potentially enabling a Si-cell with a photoelectric conversion efficiency enhancement. This paper could benefit for further exploring a promising NIR QS system in the exciting field of photonic devices and materials.</div>
