英文摘要	Single-crystal k2zncl4 doped with co2+ has been grown successfully by use of the gzochralski technique. the absorption spectrum of the crystal was measured. the most intense line. centered at 650 run. was associated with the transition (4)a(2) -> t-4(1p) and a novel and important result that corporate transition (cotransition) between (4)a(2) -> t-4(1f) and (4)a(2) -> t-4(2) of co2+ in the region of 1300-2400 nut was found and discussed. the mechanism that caused the phenomenon was explained by energy-level splitting theory. in the tetrahedral approximation, using the quantum and tanaba-sugano theories, racah parameter b and crystal field parameter 10dq were calculated. the optical energy gap, deduced to be 4.82 ev, was lower than that of pure k2zncl4.
