Free Radical Chlorination

Free Radical Chlorination. Experimental Evidence Helps to Determine Mechanism. Chlorination does not occur at room temperature in the dark . The most effective wavelength of light is blue that is strongly absorbed by Cl 2 gas.

FRET

FRET. Some limitation and disadvantages:. It should be conducted only within Forster distance Maximal overlap of donor emission and acceptor excitation High quantum yield of the donor Minimal direct excitation of the acceptor at the excitation maximum of the donor

Quantum dots

By changing the size of our quantum dots, the color of emitted light shifts from blue to near-infrared, which allows the excitation and emission of quantum dots to be highly adjustable, and brings lots of applications for highly sensitive cellular imaging, photovoltaic devices, solar cells, and light emitting devices. https://www.cd-bioparticles.com/product/quantum-dots-list-169.html
