Preparation and photo/chemical-activation of wormlike network micelles of core–shell quantum dots and block copolymer hybrids

The fluorescent interactions between amphiphilic chitosan derivatives and water-soluble quantum dots

“…As reported by Ma [16] that the photo-induced surface reconstruction of QDs surface atoms was responsible for this phenomenon, and its surface traps decreased were also reported. [28][29] When the QDs FL intensity decreased, its emission peak was red-shifted, because the QDs aggregated and its surface traps increased in a high concentration.…”

Multifunctional Nanoparticle‐Loaded Spherical and Wormlike Micelles Formed by Interfacial Instabilities

“…Given the advantages offered by wormlike, or cylindrical, micelles as nano‐carriers, in terms of providing high loading capacity of hydrophobic objects per micelle and long in vivo circulation times,35–37 preparation of nanoparticle‐loaded cylindrical micelles is of considerable interest. There have been several reports of in situ formation of nanoparticles within the cores38–40 or coronae41 of wormlike micelles, as well as adsorption of pre‐formed nanoparticles into the micelle coronae 42–44. Li et al have shown that block copolymer cylinders loaded with nanoparticles in the melt state can be dispersed in aqueous media to form cylinder micelles 45.…”

Hybrid Multilayered Plasmonic Nanostars for Coherent Random Lasing

“…Because the concentrations of AuAgNSts@SiO 2 in the R6G and MEH-PPV solutions were the same, we analyze the lasing thresholds with respect to the extinction A = ε cd of the gain materials in the stock solutions. ε is the extinction coefficient of R6G (219 mL mg –1 cm –1 taken from ref ( 41 )) or MEH-PPV (106 mL mg –1 cm –1 from ref ( 42 ) assuming that ε of MEH-PPV in chlorobenzene is in the same order of magnitude as in chloroform), c is the concentration of the gain materials, and d is the optical path of 4 mm. The extinction of the AuAgNSt@SiO 2 /R6G solutions ( c = 1.5 mg mL –1 ) is A R6G ≈ 132, while the AuAgNSt@SiO 2 /MEH-PPV solutions (5.4 mg mL –1 ) have an extinction A MEH–PPV ≈∼ 229.…”
