Abstract:

Natural microstructures in plants and animals can effectively enhance the performance of the materials, especially the hierarchical nano-porous structure, which is demonstrated to have significant positive effect on light harvesting efficiency. In order to improve the performance of calcium silicate phosphor, a leaf-templated Eu3+ doped calcium silicate phosphor was investigated with light-harvesting, luminescence and afterglow performance experiments. The results showed that the leaftemplated Eu3+ doped calcium silicate phosphor possessed a biogenic hierarchical porous structure, which is comprised of nano-pores with diameters ranging from 2.5nm, 3.0nm and 10.0～20.0nm. This structure allows a much larger surface area to interact with incident light and a higher proportion of excited Eu3+, therefore leading to enhanced light-harvesting capability in the UV-Vis range and higher light-utilization efficiency to produce stronger luminescence and prolonged afterglow.

Key words:  biomorphic material, biogenic hierarchical pores, phosphors material
