The heavy metals were detected with atomic absorption spectrum, atomic fluorescence spectrum and plasma emission spectrum, 9 heavy metals were measured quantitatively.
Allowances are made for the effects of multiple reflections on the reflector and laser rod, Xe flashlamp emission spectrum and absorption spectrum of nd doped laser glass.
The optical emission spectrum of r. f. plasma during amorphous silicon based film etching in CF4 gas is detected.
The excitation spectrum of SSA changes when its concentration is relatively higher, but the emission spectrum remains unchanged.
Its emission spectrum is marching with the crop absorbing spectrum, so it has good pertinence and high efficiency, and it is the best choice to light crops.
emission spectrum of scintillator
Secondly, the coefficients introduced in the gray-body radiation model are determined by fitting the measured emission spectrum;
New records for the luminescence power and energy emission from single events have been created, and the first time-resolved emission spectrum of sonol…
