Request for Data- Band gap of CdSe quantum dots against size

Click For Summary

Discussion Overview

The discussion centers around the request for data on the band gap of colloidal CdSe quantum dots in relation to their size, particularly focusing on those with a ZnS shell and capped with HDA. The inquiry is situated within the context of optoelectronics research.

Discussion Character

  • Exploratory, Technical explanation, Homework-related

Main Points Raised

  • David Cunnah requests data on the band gap of CdSe quantum dots as a function of size, indicating his specific interest in those with a ZnS shell.
  • One participant suggests references that may contain relevant data, listing two specific articles related to CdSe nanocrystals.
  • David expresses gratitude for the references and inquires about alternative search engines for academic articles beyond Google Scholar.
  • Claude recommends Web of Science as an alternative resource for searching articles.

Areas of Agreement / Disagreement

Participants generally agree on the usefulness of the references provided, but the discussion remains open regarding the specific data requested by David, as no direct data has been shared yet.

Contextual Notes

The discussion does not provide specific data on the band gap of CdSe quantum dots, and the references suggested may have varying relevance depending on the specific size range and conditions of the quantum dots in question.

Who May Find This Useful

Researchers and students in the fields of optoelectronics, materials science, and nanotechnology may find this discussion relevant, particularly those interested in quantum dot properties and literature search strategies.

Would anybody be able to provide me with data concerning the band gap of colloidal CdSe quantum dots against their size?? I am currently using CdSe dots with a ZnS shell, capped with HDA. Any relevant information would be much appreciated.
Many thanks,

You might find something in the references from one of these:

1. "Lateral Patterning of Luminescent CdSe Nanocrystals by Selective Dewetting from Self-Assembled Organic Templates", N. Lu, et al Nano Letters 4, 885 (2004)

2. "Highly emissive colloidal CdSe/CdS heterostructures of mixed dimensionality" D. V. Talapin , et al Nano Letters 3, 1677 (2003)
 
Thanks!

Very helpful! Thank you!
Out of interest are there any search engines other than googlescholar you recommend for searching for articles??
