Does varying the excitation wavelength affect the emission wavelength?

I excited a fused aromatic conjugated naphthalene-based system from 240-360 nm and the emission bank was continuously red shifted from 500-800 nm. The absorption maximum is around 360 nm.

Dr. Ojo,

You can use pass H2 gas under certain temperatures to reduce the surface of the crystal. You need to find the best working temperature with your tests.

Good luck

Recrystallize it ! but this time filter and save under N2.

Shalin Kumar

Do recrystallization process or pass them with anti -oxidant gases to retain them.
