Abstract
Even though the core–shell nanomaterials were reported as the most efficient up-conversion materials to achieve the energy migration, the light transmission mechanism in core-shell heterostructure and the energy loss induced by multilayer shells have not been studied. In this work, we report the admittance recursive method to simulate the transmission process of TE and TM waves and calculate the light transmission efficiency in core-shell heterostructure. The effects of multilayer shell thickness, wavelength of transmitted light, and critical angle on the light transmittance of core-shell nanoparticles (NPs) are studied. It is found that the TE wave transmission efficiency from NaYF4@SiO2 core-shell heterostructure can reach more than 96.4%, while the values of transmission efficiency of TE and TM waves are less than 40% in NaYF4@SiO2@Ag core-shell-shell heterostructure. Only 1540 nm and 980 nm infrared lights transmit from the NaYF4@Ag@SiO2@Ag multilayer shell heterostructure.
