Narrow-band absorption-enhanced quantum dot/J-aggregate conjugates.
We report narrow-band absorption enhancement of semiconductor nanocrystals via Förster resonance energy transfer from cyanine J-aggregates. These J-aggregated dyes associate electrostatically with short quantum-dot (QD) surface ligands in solution. Energy transfer efficiencies approach unity for this light sensitization and result in a 5-fold enhancement in the QD excitation near the J-aggregat...
متن کاملQuantum-enhanced absorption refrigerators
Thermodynamics is a branch of science blessed by an unparalleled combination of generality of scope and formal simplicity. Based on few natural assumptions together with the four laws, it sets the boundaries between possible and impossible in macroscopic aggregates of matter. This triggered groundbreaking achievements in physics, chemistry and engineering over the last two centuries. Close anal...
متن کاملEnhanced Blood Vessels in Laparoscopy by Using Narrow-Band Imaging
In laparoscopic surgeries, because of lack of tactile sensation and 3D visual feedback, it is difficult to identify the position of blood vessels intraoperatively. An accidental injury to a blood vessel could result in change of laparoscopic procedures to open surgery. A noninvasive, reliable, and economical method to detect blood vessels during laparoscopic and endoscopic procedures would be v...
متن کاملNarrow-Band Single Photons as Carriers of Quantum Information
The use of quantum mechanical properties for information processing, the socalled quantum information processing (QIP) has become an increasingly popular research field in the last two decades. It turned out that single photons are the most reliable long distance carriers of quantum information, e.g., tools to connect different processing nodes in QIP. While several methods exist to produce sin...
متن کاملA Design of Narrow-Band Band-Pass
C l c3 Abstract-In this paper, a design method is described for low-sensitivity narrow-band band-pass switched-capacitor filters (SCF's) using a pseudo-2-path principle and a capacitor-error-free voltage inversion. The proposed method is based on the low-pass to high-pass transformation using voltage inversion, the pseudo2-path principle, the capacitance-ratio reduction technique and a very low...
