  • Quick comment (not a full review): The hook wording gives the inaccurate indication that all nanocrystals exhibit this behavior. That is absolutely not true. The hook should be reworded to fix that. --Orlady (talk) 13:16, 6 September 2012 (UTC)
  • Hopefully it is ok to respond here. Thanks for taking an interest in this DYK entry. I will review the sources and see what I can come up with. ---- Steve Quinn (talk) 04:46, 11 September 2012 (UTC)
  • We really need a new hook, as it does not look to be correct. Graeme Bartlett (talk) 07:55, 13 September 2012 (UTC)
After reading the article and several of the sources, I have stricken through the original hook and am suggesting two new ones:
Someone else will have to review these suggestions. I found this source (cited once in the article, as footnote 2, but not cited in connection with the hook fact) to be a particularly accessible summary of the topic highlighted in the hook. I have a concern about the title and some wording in the article section entitled "Random behavor." The behavior of these nanocrystals likely is not truly random; it's just that people haven't satisfactorily explained it yet. Indeed, research reports like this one and some of the sources cited in the article are starting to provide explanations for the behavior. This is why my proposed ALT2 hook uses the word "unpredictably" instead of "random" or "without explanation". --Orlady (talk) 15:22, 14 September 2012 (UTC)
  • Needs full review, including two proposed ALT hooks. BlueMoonset (talk) 01:54, 17 September 2012 (UTC)
63% of the article is a verbatim copy of this public domain source: [1]. The source is properly attributed, so it passes the article guidelines, but I count barely 1600 characters of new prose, some of which is still a close paraphrase. Rule 2b excludes such text from the length count, so it's right on the edge of eligibility. Also, the lead does need to be clarified to reflect fact that (I think, according to Ref. 2) blinking is a property of all semiconductor nanocrystals, except for ones specifically made to avoid it, and not just CdSe nanocrystals; the title of this article should really be Blinking in semiconductor nanocrystals. Otherwise, it is new enough and suitably referenced, and no QPQ review is needed since I only see evidence of three previous DYK credits. I've revised ALT1 and ALT2 to reflect that the article is about the blinking behavior rather than the nanocrystals themselves, which are covered by the article Quantum dot.

Glad this finally got a review, and that the reviewer was able to access that public domain source (I've not been able to get that page to load). Another wrinkle: This article also seems to overlap in scope with Fluorescence intermittency. --Orlady (talk) 15:06, 24 September 2012 (UTC)
Well, fluorescence intermittency is also a property of organic dyes. I'm okay with the articles being separate, but this isn't really a DYK review issue anyhow. Antony–22 (talk⁄contribs) 21:26, 25 September 2012 (UTC)
I can finally see the NRL source. I see that this article is highly derivative of that source -- that will need to be resolved if we are going to use it at DYK. The apparent existence of other articles about the same phenomenon is relevant to DYK because it relates to whether this article is new content. Also, the issue with the unclear lead needs to be resolved. --Orlady (talk) 16:21, 7 October 2012 (UTC)
Not dealt with. — Crisco 1492 (talk) 14:09, 14 October 2012 (UTC)
At least one or more of the sources says this blinking occurs randomly. Also, as far as I can tell from the sources, this is a phenonemnon that occurs in all types of nanocrystals. Unfortunately, due to time constraints I am unable to do a lot of work with this article right now, and I am the one who really should point out the source or sources that indicate this random blinking is common across nanocrystals. In any case, I withdraw my request for DYK nomination. Thank you all for your interest. --- Steve Quinn (talk) 03:48, 15 October 2012 (UTC)
