文摘

CdSeTe@TiO2nanotubes were prepared with insitu growth process (*). CdSeTe@ TNTs were used as high efficient visible-light photocatalysts. CdSeTe@TNTs show a high photoinduced electron transfer rate of 7.98 × 109 s−1. Ternary-alloyed CdTeSe QDs exhibit a long fluorescence lifetime of 105.82 ns. The absorption edge of CdTeSe@TNTs is red shifted significantly toward 697 nm.
