Does the human body emit infrared radiation? Can light reflect light? Does melanin absorb light? Is light reflected or refracted? Does the sun reflect light? Can a mirror reflect a laser? Why doesn't the hydrogen molecule absorb infrared light?
We present the results of recent investigations into the production, isolation and optical characterization of erbium metallofullerenes. Near-infrared emission from Er 3+ has been previously observed from Er 2@C 82. However, Er 2@C 82 cannot be responsible for all of the observed emission near ...
or light waves, of a surprisingly high intensity were being emitted from the seedlings. In case the light had to do with an effect of photosynthesis, they decided that their next test -- with potatoes -- would be to grow the seedling plants in the dark. This time...
