Plasmon assisted intense blue–green emission from ZnO/ZnS nanocrystallites

Structural and optical properties of monodispersed ZnS/CdS/ZnO and ZnO/ZnS/CdS nanoparticles

“…For the ZnO/ZnS core-shell nanoparticles, Li et al [38] observed an asymmetric two weak blue shoulder emission peaks at around 446 nm and 465 nm. Mandal et al [39] have also studied the optical property of the ZnO/ZnS nanoparticles and observed two strong peaks at 438 and 505 nm [39]. However in the present study, an enhanced, symmetric and single peak was observed at 490 nm for the ZnO/ZnS core-shell nanoparticles coated by a CdS layer.…”

ZnO/ZnS core–shell quantum dots with enhanced ultraviolet fluorescence and low cytotoxicity for cell imaging

“…Sadollahkhani [31] and Sanad et al [32] prepared ZnO@ZnS nanocomposites, but both the UV and visible emission were suppressed. Although enhanced visible fluorescence was found by some researchers [33,34], the maximum PL intensity of ZnO/ZnS is still lower than that of ZnO. The reason for the poor PL performance of ZnO/ZnS can be attributed to the formation of a type-II coreshell structure.…”

Insight into the eigenmodes of plasmonic nanoclusters based on the Green’s tensor method

“…Metallic nanostructures supporting plasmon resonances have been used in various applications such as SERS [1][2][3][4][5], biosensing [6][7][8][9], plasmonic trapping [10][11][12], and fluorescence enhancement [13][14][15][16][17][18]. Optimization of a plasmonic structure for a particular application is made easier via the use of various computational tools.…”
