We also report a simple solution\u2010based method for the preparation of high quality CdS QDs and CdS QRs at relatively low temperature. The observed quenching of PL intensities are 78.8\u2009% and 63.8\u2009% for CdS QDs and QRs, respectively in the presence of Nile Red dye. The calculated energy\u2010transfer efficiencies are 45\u2009% and 19\u2009% from QDs and QRs to dyes, respectively. The energy transfer varies with changing the shape of the nanoparticles. The estimated F\u00f6rster distances (R<jats:sub>0<\/jats:sub>) are 37.8 and 33.8 \u00c5 for CdS QDs and QRs, respectively. In the present study, the estimated distances (r) between one donor and one acceptor are 39.1 and 43.1 \u00c5 for QDs and QRs, respectively, using the efficiency of F\u00f6rster resonance energy transfer (FRET) which depends on the inverse sixth power of the distance of separations between one nanocrystal and one dye molecule. Considering single donor and multiple acceptors interactions, the calculated average distances (r<jats:italic><jats:sub>n<\/jats:sub><\/jats:italic>) between the donor and acceptor are 47.7 and 53.9 \u00c5 for QD\u2019s and QR\u2019s, respectively. The steady\u2010state and time\u2010resolved spectroscopic analysis of nanoassemblies confirm the formation of one donor and multiple acceptors.<\/jats:p>","DOI":"10.1002\/cphc.200800298","type":"journal-article","created":{"date-parts":[[2008,8,29]],"date-time":"2008-08-29T06:01:47Z","timestamp":1219989707000},"page":"2052-2058","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":42,"title":["Donor\u2013Acceptor Systems: Energy Transfer from CdS Quantum Dots\/Rods to Nile Red Dye"],"prefix":"10.1002","volume":"9","author":[{"given":"Suparna","family":"Sadhu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amitava","family":"Patra","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2008,9,30]]},"reference":[{"key":"e_1_2_6_1_2","doi-asserted-by":"publisher","DOI":"10.1038\/nmat961"},{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja063415e"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja071457c"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja037088b"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja0685452"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1039\/b508911e"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.cplett.2005.07.088"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja068095d"},{"key":"e_1_2_6_9_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja0773406"},{"key":"e_1_2_6_10_2","doi-asserted-by":"publisher","DOI":"10.1021\/jp7114753"},{"key":"e_1_2_6_11_2","doi-asserted-by":"crossref","DOI":"10.1007\/978-1-4757-3061-6","volume-title":"Principles of Fluorescence Spectroscopy, 2nd ed.","author":"Lakowicz J.
