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 ...

Magnetic blue shift of Mott gaps enhanced by double exchange [PDF]
Physical Review Research, 2021 A substantial energy gap of charge excitations induced by strong correlations is the characteristic feature of Mott insulators. We study how the Mott gap is affected by long-range antiferromagnetic order. Our key finding is that the Mott gap is increased

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.

A Large Blue Shift of the Biexciton State in Tellurium Doped CdSe Colloidal Quantum Dots [PDF]
, 2008 The exciton-exciton interaction energy of Tellurium doped CdSe colloidal quantum dots is experimentally investigated. The dots exhibit a strong Coulomb repulsion between the two excitons, which results in a huge measured biexciton blue shift of up to 300

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)
