| 中文摘要 | combination with semiconductors is a promising approach to the realization of broadband excitation of light conversion materials based on rare earth compounds, to boost the energy efficiency of silicon solar cells. cd1-xznxs is a wide bandgap semiconductor with large exciton binding energy. by changing its composition, the bandgap of cd1-xznxs can be tuned to match the absorption of trivalent lanthanide (ln) ions, which makes it a competent energy donor for the ln(3+)-yb3+ couple. in this work, we designed a clean route to a broadband down-converter based on a core-shell-like y2o3:[(tb3+-yb3+), li+]/cd0.81zn0.19s (cdzns) heterostructure. by hot-pressing and subsequent annealing of a y2o3:[(tb3+ -yb3+), li+]/cdzns mixture, highly pure cdzns was sublimated and deposited on the y2o3:[(tb3+-yb3+), li+] grains while maintaining the original composition of the precursor. the cdzns shell acted as a light absorber and energy donor for the tb3+-yb3+ quantum cutting couple. because the use of solvents was avoided during the formation of the heterostructures, few impurities were incorporated into the samples, and the non-radiative transition was therefore markedly suppressed. the y2o3:[(tb3+-yb3+), li+]/cdzns heterostructures possess strong near-infrared (nir) luminescence from yb3+. broadband down-conversion to the yb3+ nir emission was obtained in a wide range of 250-650 nm. |
