Quantum Dot-Induced Blue Shift of Surface Plasmon Spectroscopy [PDF]
Nanomaterials, 2022 We experimentally demonstrate the spectral blue shift of surface plasmon resonance through the resonant coupling between quantum dots (QDs) and surface plasmons, surprisingly in contrast to the conventionally observed red shift of plasmon spectroscopy ...

Coexistence of the Band Filling Effect and Trap-State Filling in the Size-Dependent Photoluminescence Blue Shift of MAPbBr3 Nanoparticles [PDF]
NanomaterialsThe size-dependent photoluminescence (PL) blue shift in organometal halide perovskite nanoparticles has traditionally been attributed to quantum confinement effects (QCEs), irrespective of nanoparticle size.

Blue shift of spontaneous emission in hyperbolic metamaterial. [PDF]
Sci Rep, 2014 Spontaneous emission is one of the most fundamental quantum phenomena in optics. Following the seminal work of Purcell and in agreement with the Fermi's Golden Rule, its rate can be controlled with the photonic density of states (PDOS). In recent years, this effect has been demonstrated in metamaterials with hyperbolic dispersion--highly anisotropic ...

Blue-light background impairs visual exogenous attention shift
Scientific Reports, 2023 Previous research into the effects of blue light on visual-spatial attention has yielded mixed results due to a lack of properly controlling critical factors like S-cone stimulation, ipRGCs stimulation, and color.

Quntitative structure activity relationship (QSAR) of UV-visible spectrum of some different chalkons [PDF]
شیمی کاربردی روز, 2013 Â The UV-visible spectrum of some different chalkons with both electron with-drawing and electron-donating groups have been investigated. The results showed that electron with-drawing groups cause Blue-Shift and electron-donating groups cause Red-Shift.

High Hydrogen Ion Concentration Causes a Blue Shift in Gold Nanoparticles
Crystals, 2021 In this research, our team used a rare electrochemical method to obtain gold nanoparticles (GNPs). The growth solution has been added with nitric acid in order to observe the effect of GNPs. The solution also included cetyltrimethylammonium bromide (CTAB)
