For the growth of the CdTe core, the TOPTe\/TOP solution was swiftly added to the CdO\/TOP solution at a higher temperature (300\u2009\u00b0C) than the growth temperature (250\u2009\u00b0C). For the growth of the CdSe shell, in contrast, the CdO\/TOPSe\/TOP solution was slowly added to the CdTe\/TOP solution at a lower temperature than the growth temperature (200\u2013240\u2009\u00b0C). The temporal evolution of the optical properties of the growing core\u2013shell nanocrystals was monitored in detail. During the growth of the CdSe shell, the core\u2013shell nanocrystals exhibited interesting changes in photoluminescence (PL) properties. The highest PL efficiency (\u224838\u2009%) was detected from core\u2013shell nanocrystals with a CdSe shell thickness of 0.4\u20130.5\u2005nm (indicated by TEM); the formation of the first monolayer is proposed. Our synthetic approach is well suited to a practical realization of engineering materials with bandgaps in the near\u2010IR and IR spectral ranges.<\/jats:p>","DOI":"10.1002\/smll.200400069","type":"journal-article","created":{"date-parts":[[2004,12,21]],"date-time":"2004-12-21T13:25:09Z","timestamp":1103635509000},"page":"332-338","source":"Crossref","is-referenced-by-count":127,"title":["Sequential Synthesis of Type\u2005II Colloidal CdTe\/CdSe Core\u2013Shell Nanocrystals"],"prefix":"10.1002","volume":"1","author":[{"given":"Kui","family":"Yu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Badruz","family":"Zaman","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Svetlana","family":"Romanova","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Da\u2010shan","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John A.","family":"Ripmeester","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2005,1,28]]},"reference":[{"key":"e_1_2_6_1_2","unstructured":"\u00a0"},{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1002\/adma.19930050204"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1038\/370354a0"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.281.5385.2016"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1386-9477(02)00374-0"},{"key":"e_1_2_6_6_2","unstructured":"\u00a0"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.1021\/jp9530562"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja970754m"},{"key":"e_1_2_6_9_2","doi-asserted-by":"publisher","DOI":"10.1021\/jp971091y"},{"key":"e_1_2_6_10_2","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1521-3757(19991216)111:24<3913::AID-ANGE3913>3.0.CO;2-C"},{"key":"e_1_2_6_10_3","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1521-3773(19991216)38:24<3692::AID-ANIE3692>3.0.CO;2-W"},{"key":"e_1_2_6_11_2","doi-asserted-by":"publisher","DOI":"10.1021\/jp9943676"},{"key":"e_1_2_6_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0038-1098(98)00349-4"},{"key":"e_1_2_6_13_2","doi-asserted-by":"publisher","DOI":"10.1063\/1.121249"},{"key":"e_1_2_6_14_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja0361749"},{"key":"e_1_2_6_15_2","doi-asserted-by":"publisher","DOI":"10.1021\/la049202p"},{"key":"e_1_2_6_16_2","doi-asserted-by":"publisher","DOI":"10.1016\/0022-0248(94)90879-6"},{"key":"e_1_2_6_17_2","unstructured":"\u00a0"},{"key":"e_1_2_6_18_2","doi-asserted-by":"publisher","DOI":"10.1201\/9780585139401"},{"key":"e_1_2_6_19_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1359-0294(98)80014-9"},{"key":"e_1_2_6_20_2","unstructured":"\u00a0"},{"key":"e_1_2_6_21_2","doi-asserted-by":"publisher","DOI":"10.1016\/0014-3057(71)90036-X"},{"key":"e_1_2_6_22_2","first-page":"35","volume":"4","author":"O'Malley J.
