Preferred Label : photon fluence;
Detailed label : photon fluence, Hp,o, Fp,o;
IUPAC definition : Amount of photons (quanta of radiation) incident on a small sphere from u all directions
/u , divided by the cross-sectional area of that sphere and integrated over time.
Photons per surface area (quanta m-2). SI unit is m-2.;
Scope note : this quantity can be used on a chemical amount basis by dividing hp,o by the avogadro
constant, the symbol then being hn,p,o, the name photon fluence, amount basis, si
unit is mol m-2;common unit is einstein m-2.; mathematical definition: hp,o fp,o np s t t ep,o
with ep,o the photon fluence rate, integrated over the duration of the irradiation,t.
if ep,ois constant over the time interval, hp,o fp,o ep,o t;
Origin ID : P04634;
