Igama elithi excimer libhekisela esimweni se-athomu sesikhashana lapho ama-athomu anamandla aphezulu akha khona ama-molecule pair ahlala isikhathi esifushane, nomaama-dimer, uma kushukunyiswa ngogesi. Laba bobabili babizwa ngokuthiama-dimers ajabuleNjengoba ama-dimer ajabule ebuyela esimweni sawo sokuqala, amandla asele akhishwa njenge-photon ye-ultraviolet C (UVC).
Ngawo-1960, i-portmanteau entsha,umhloli, yavela emphakathini wesayensi futhi yaba yigama elamukelekayo lokuchaza ama-dimer ajabule.
Ngokwencazelo, igama elithi excimer libhekisela kuphela ku-izibopho ze-homodimericphakathi kwama-molecule ohlobo olufanayo. Isibonelo, esibanini se-xenon (Xe) excimer, ama-athomu e-Xe anamandla aphezulu akha ama-dimer e-Xe2 avuselelwe. Lawa ma-dimer aphumela ekukhishweni kwama-photon e-UV kubude be-wavelength obungu-172 nm, okusetshenziswa kabanzi embonini ngezinjongo zokusebenzisa ubuso.
Uma kwenzeka ama-complexes ajabulisayo akhiwei-heterodimeric(ezimbili ezahlukene) izinhlobo zesakhiwo, igama elisemthethweni le-molecule ephumayo yilelii-exciplexAma-exciplex e-Krypton-chloride (KrCl) ayafiseleka ngenxa yokukhipha kwawo ama-photon e-ultraviolet angu-222 nm. Ubude be-wavelength obungu-222 nm baziwa ngamakhono awo amahle kakhulu okulwa nokubulala amagciwane.
Kuyavunywa ngokuvamile ukuthi igama elithi excimer lingasetshenziswa ukuchaza ukwakheka kwemisebe ye-excimer kanye ne-exciplex, futhi lidale leli gama.i-excilampuma kukhulunywa ngama-emitters asebenzisa i-excimer asuselwe ekukhipheni.
