The emission spectra of two star polymers (star poly VBCz) and star poly CzEMA)) in the solid state displayed red light emission, while those of two monomers showed blue light emission.
Despite these appealing features, the emission in solid state is red-shifted to the yellow region, owing to its aggregation character.
When going from solution to the solid state, both polymers are red-shifted approximately 20 nm and the slightly red-shifted absorption maximum of BBTI-1 (722 nm) relative to BBTI-2 (716 nm) is thus also observed in the solid state.
The chemical composition, morphology and configuration of a series of solid lactide-glycolide copolymers (PLAXGAY: X, % l-lactide and Y, % glycolide) were studied by solid state 13C n.m.r., infra-red and Raman spectroscopy.
By understanding the mechanism of energy transfer from ZnO-nc to Eu3+ ions and optimising the fabrication parameters in producing the highest red emission from Eu3+ ions, we can make future proficient red luminescent solid state devices based on a low-cost technique.
Their emission color can be tuned from green to orange in tetrahydrofuran/H2O solutions, from green to red in solid state or pure tetrahydrofuran solutions.
The investigation of photophysical and electrochemical properties reveals that this compound can exhibit broad and strong absorption band at the range of 300 700 nm with a low energy gap in solid state, meanwhile it exhibits highly red fluorescent emission and large Stokes shifts.
– 64GB solid state drive: This is the biggest red flag, as far as I'm concerned.
Here, using these luminogenic molecules, a series of new purely organic phosphors are color-tuned to emit yellow, aurantiacus, orange, nacarat and red in the solid state, which are promising candidates for potential applications in organic light-emitting diodes for display.
Confocal microscopy was performed with a Leica TCS SP2 AOBS confocal microscope, equipped with yellow (Argon, 488 nm), red (561 nm solid state laser) and blue (633 nm HeNe laser) excitation laser lines.
