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.

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.

Observation of Ultrashort Laser Pulse Evolution in a Silicon Photonic Crystal Waveguide
Micromachines, 2021 Using the sum frequency generation cross-correlation frequency-resolved optical gating (SFG-XFROG) measurement setup, we observed the soliton evolution of low energy pulse in an Si photonic crystal waveguide, and it exhibited the pulse broadening, blue ...

Dynamic Responses of Cylindrical Whispering Gallery Mode Revealed by Axial Liquid Disturbance
IEEE Photonics Journal, 2020 Cylindrical whispering gallery mode (WGM) microresonators have achieved much attention in the sensing field due to high sensitivity, compatibility and integration. The excitation of spiral modes in such a resonator is unavoidable, causing the axial field
