Finds documents with exactly this word group, in exactly this word order and spelling (e.g. "employer branding").
Finds documents with both search terms (e.g. sales AND bonus).
Finds documents with one or the other search term (e.g. porsche OR volkswagen).
Finds documents with all search terms. Blank space is understood as AND (e.g. man robot production).
Finds documents with no appearance of the word behind NOT (e.g. ford NOT "harrison ford").
Finds documents where the search term is mentioned at least "n" times."n" may be any number (e.g. COUNT(gear)>8).
Finds documents with both search terms in any word order, permitting "n" words as a maximum distance between them. Best choose between 15 and 30 (e.g. NEAR(recruit, professionals, 20)).
Finds documents with the search term in word versions or composites. The asterisk * marks whether you wish them BEFORE, BEHIND, or BEFORE and BEHIND the search term (e.g. lightweight*, *lightweight, *lightweight*).
Finds documents with the search term in different spellings. "?" allows only one character (e.g. organi?ation).
Special characters are understood as AND (e.g. Miller Bros. & Sons).

Abstract

We have observed the structure and luminescence properties of CdSe/CdS-cellulose nanocomposites (CCCNC) and characterized it. The CCCNC is composed of two component materials, nanocrystalline CdSe/CdS core–shell QDs and nanocrystalline cellulose. The structural and optical characteristics of CCCNC were analysed using XRD, TEM, PL and I–V characteristic techniques. A spherical phosphor particle of dimension about 14 nm was confirmed by TEM. The characteristic X-ray diffraction planes of the said QDs as (100), (002) and (101) were found out to be superimposed at the tail of the most intense plane (002) of cellulose. Sharp photoluminescence peak at 650 nm and absorption spectra indicate that the distributions of quantum size possess rigid structure of the entire shell. It is expected that the present study will have high promise for X-ray-induced photoluminescence-based sensing application.
