Lub sij hawm excimer yog hais txog ib ntus atomic lub xeev nyob rau hauv uas high-zog atoms tsim short-lived molecular khub, los yogdimers, thaum hluav taws xob zoo siab. Cov khub no hu uazoo siab dimers. Raws li qhov zoo siab dimers rov qab mus rau lawv lub xeev qub, lub zog seem raug tso tawm raws li ultraviolet C (UVC) photon.
Nyob rau xyoo 1960, ib lub portmanteau tshiab,excimer, tau tshwm sim los ntawm lub zej zog kev tshawb fawb thiab tau los ua lub sij hawm lees paub los piav txog kev zoo siab dimers.
Los ntawm kev txhais, lo lus excimer tsuas yog hais txoghomodimeric bondsnruab nrab ntawm cov molecules ntawm tib hom. Piv txwv li, nyob rau hauv ib tug xenon (Xe) excimer teeb, high-zog Xe atoms tsim zoo siab Xe2 dimers. Cov dimers no ua rau kev tso tawm ntawm UV photons ntawm lub wavelength ntawm 172 nm, uas yog siv dav hauv kev lag luam rau lub hom phiaj ua kom ntog.
Nyob rau hauv cov ntaub ntawv ntawm zoo siab complexes tsim ntawmheterodimeric(ob qhov sib txawv) hom qauv, lub sij hawm ua haujlwm rau qhov tshwm sim molecule yogexciplex. Krypton-chloride (KrCl) exciplexes xav tau rau lawv cov emission ntawm 222 nm ultraviolet photons. Lub 222 nm wavelength paub txog nws cov peev xwm tiv thaiv kab mob microbial zoo heev.
Nws feem ntau lees txais tias lo lus excimer tuaj yeem siv los piav qhia txog kev tsim ntawm ob qho tib si excimer thiab exciplex hluav taws xob, thiab tau ua rau lub sijhawm.excilamThaum xa mus rau kev tso tawm raws li excimer emitters.
