When the concentration of the actual quenching agent is varied, the rate of electron transfer and the degree of phosphorescence is affected.
42.
The title alludes to the mysterious phenomenon of phosphorescence of the sea, and it was amongst the treasures lost in the 1970 fire.
43.
Although he is aware that the phosphorescence is caused by luminous bacteria, Weinschadt derives great satisfaction from playing a part in the ignition.
44.
Radioluminescence uses the radioactive decay of tritium to light the sign, while phosphorescence uses light-emitting phosphors to glow in the dark.
45.
Fluorescent materials cease to glow immediately when the radiation source stops, unlike phosphorescence, where it continues to emit light for some time after.
46.
Decay from triplet states ( phosphorescence ) is spin forbidden, increasing the timescale of the transition and limiting the internal efficiency of fluorescent devices.
47.
This two-input logic gate is the first of its kind and displays non-commutative behaviour with chemical inputs and a phosphorescence output.
48.
For the Kanaka, the phosphorescences of the night are from the spirit of the dead, they believe they are there and fear them.
49.
Since the electron transfer step of the catalytic cycle takes place from the triplet excited state, it competes with phosphorescence as a relaxation pathway.
50.
At night we saw swirling phosphorescence-- mesmerizing underwater fireworks-- and a brilliant starry sky with an awesome Milky Way and Southern Cross.
