Their photophysical properties are investigated via the interband CdSe\u2192ZnTe emission and its associated relaxation dynamics.

Capping CdSe\/CdTe with ZnTe results in a distant electron\u2013hole separation between CdSe (electron) and ZnTe (hole) via an intermediate CdTe layer. In the case of the CdSe\/CdTe\/ZnTe structure, a lifetime as long as 150\u2005ns is observed for the CdSe\u2192ZnTe (1415\u2005nm) emission. This result further indicates an enormously long radiative lifetime of \u224810\u2005ms. Upon excitation of the CdSe\/CdTe\/ZnTe structure, the long\u2010lived charge separation may further serve as an excellent hole carrier for catalyzing the redox oxidation reaction.<\/jats:italic><\/jats:p>","DOI":"10.1002\/smll.200500227","type":"journal-article","created":{"date-parts":[[2005,10,11]],"date-time":"2005-10-11T08:47:31Z","timestamp":1129020451000},"page":"1215-1220","source":"Crossref","is-referenced-by-count":72,"title":["Type\u2010II CdSe\/CdTe\/ZnTe (Core\u2013Shell\u2013Shell) Quantum Dots with Cascade Band Edges: The Separation of Electron (at CdSe) and Hole (at ZnTe) by the CdTe Layer"],"prefix":"10.1002","volume":"1","author":[{"given":"Chun\u2010Yen","family":"Chen","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chiu\u2010Ting","family":"Cheng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chih\u2010Wei","family":"Lai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ya\u2010Hui","family":"Hu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pi\u2010Tai","family":"Chou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yi\u2010Hsuan","family":"Chou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hsin\u2010Tien","family":"Chiu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2005,10,28]]},"reference":[{"key":"e_1_2_6_1_2","unstructured":"\u00a0"},{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.271.5251.933"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1021\/cm9503137"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1021\/jp971091y"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.1021\/ar9700320"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja002535y"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.1021\/nl0155126"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.1021\/nl025596y"},{"key":"e_1_2_6_9_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja0361749"},{"key":"e_1_2_6_10_2","doi-asserted-by":"publisher","DOI":"10.1021\/jp049177w"},{"key":"e_1_2_6_11_2","doi-asserted-by":"publisher","DOI":"10.1038\/nbt920"},{"key":"e_1_2_6_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcrysgro.2004.01.064"},{"key":"e_1_2_6_13_2","doi-asserted-by":"publisher","DOI":"10.1021\/jp050767j"},{"key":"e_1_2_6_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0039-6028(03)00571-5"},{"key":"e_1_2_6_15_2","volume-title":"Practical Surface Analysis: Auger and X\u2010ray Photoelectron Spectroscopy,","year":"1993"},{"key":"e_1_2_6_16_2","volume-title":"Handbook of X\u2010ray Photoelectron Spectroscopy","author":"Wagner C.
