Surface plasmon resonance enhancement of photoluminescence intensity and bioimaging application of gold nanorod@CdSe/ZnS quantum dots
Beilstein J. Nanotechnol. 2019, 10, 22–31, doi:10.3762/bjnano.10.3
- QDs have an apparent PL enhancement of four-times after binding with GNRs. In addition, in vitro experimental results show that the biostability of the GNR@CdSe/ZnS nanoparticles can be improved by using folic acid. A bioimaging study has also been performed where GNR@CdSe/ZnS nanoparticles were used
- fluorescence enhancement by organizing QDs on GNRs, and Anjali Kshirsagar et al. reported the electronic structure of free-standing and gold-attached passivated CdSe nanorods [24][25]. These studies covered the synthesis of GNR@CdSe/ZnS nanoparticles using different methods; however, most of these synthesis
- methods are complicated, and it is difficult to reproduce their preparation and desired applications. It is desirable to find a simple method to synthesize GNR@CdSe/ZnS nanoparticles in aqueous-phase which exhibit high PL emission and optimize the bioconjugated surfaces of these nanoparticles for
A facile method for the preparation of bifunctional Mn:ZnS/ZnS/Fe3O4 magnetic and fluorescent nanocrystals

- , Millipore Corporation) as the solvent. Synthesis of Mn:ZnS/ZnS QDs The Mn:ZnS/ZnS nanoparticles were prepared in basic aqueous solution at 100 °C using MPA as a ligand. The synthesis was carried out according to the procedure detailed in our previous work [37]. The obtained colloidal solution of Mn:ZnS/ZnS
Structural, optical, opto-thermal and thermal properties of ZnS–PVA nanofluids synthesized through a radiolytic approach
Beilstein J. Nanotechnol. 2015, 6, 529–536, doi:10.3762/bjnano.6.55
- nanofluids consisting of ZnS nanoparticles homogeneously distributed in a PVA solution. The ZnS nanoparticles were formed by the electrostatic force between zinc and sulfur ions induced by gamma irradiation at a dose range from 10 to 50 kGy. Several experimental characterizations were conducted to
- , powder X-ray diffraction (XRD) for confirming the formation and crystalline structure of ZnS nanoparticles, UV–visible spectroscopy for measuring the electronic absorption characteristics, transient hot wire (THW) and photoacoustic measurements for measuring the thermal conductivity and thermal
- effusivity of the samples, from which, for the first time, the values of specific heat and thermal diffusivity of the samples were then calculated.

Preparation of poly(N-vinylpyrrolidone)-stabilized ZnO colloid nanoparticles
Beilstein J. Nanotechnol. 2014, 5, 402–406, doi:10.3762/bjnano.5.47
- PVP-protected gold atomic clusters [16], and a broad luminescence band centered at 440 nm was found in PVP-capped ZnS nanoparticles [17]. The colloidal ZnO/PVP/methanol solution, apart from the most intense PL band at 356 nm coming from the PVP, exhibits a strong PL band at 376 nm (3.30 eV), which
Distance dependence of near-field fluorescence enhancement and quenching of single quantum dots
Beilstein J. Nanotechnol. 2011, 2, 645–652, doi:10.3762/bjnano.2.68
- sulphuric acid 96% and hydrogen peroxide 30%) for one minute, rinsed thoroughly with MilliQ filtered water and dried with nitrogen. After cleaning, hydrophobic fluorescent CdSe/ZnS nanoparticles [29] with a spectral emission maximum at 585 nm were diluted in n-heptane (Sigma Aldrich), microdispensed to the
