摘要：
In weakly excited low-pressure BCl3/N2 discharges, the emission intensity of the first positive N2 system decreases steeply with increasing BCl3 molar fraction, while the emissions of BCl and atomic boron exhibit narrow maxima at BCl3 molar fractions of 1 and 0.4%, respectively. From the molar fraction dependence of the electron density and of the N2 second positive emission, it is concluded that electron impact excitation is not responsible for the observed BCl and B emissions. An energy transfer from the N2(W) state to BCl(x) species can explain the results.
