Laser‐induced fluorescence of the HgZn excimer: The 460 nm band

The 460 nm HgZn fluorescence band was excited by pumping a Hg‐Zn vapor mixture in a quartz cell with 307.59 nm laser pulses which populated the 43P1 Zn atomic state. The excited HgZn molecules were formed by collisions of the 43P1 Zn atoms with ground‐state Hg atoms. The resulting HgZn fluorescent band centered near 460 nm had a half‐width of about 80 nm and contained an additional component near 500 nm.
