Igama elithi excimer libhekisela esimweni se-athomu yesikhashana lapho ama-athomu anamandla amakhulu akha amapheya e-molecular ehlala isikhashana, nomaama-dimers, lapho ngijabule ngogesi. Lawa mapheya abizwaama-dimers ajabule. Njengoba ama-dimer ajabulile ebuyela esimweni sawo sokuqala, amandla ayinsalela akhululwa njenge-photon ye-ultraviolet C (UVC).
Ngawo-1960, i-portmanteau entsha,i-excimer, yavela emphakathini wesayensi futhi yaba yigama elamukelekayo lokuchaza ama-dimers ajabulile.
Ngokwencazelo, igama elithi excimer libhekisela kuphelaamabhondi e-homodimericphakathi kwama-molecule ohlobo olufanayo. Isibonelo, kusibani se-xenon (Xe) se-excimer, ama-athomu e-Xe anamandla enza ama-Xe2 dimers ajabulile. Lawa ma-dimers aphumela ekukhishweni kwama-photon e-UV kubude begagasi obungu-172 nm, asetshenziswa kakhulu embonini ngezinjongo zokwenza kusebenze ngaphezulu.
Endabeni yezakhiwo ezijabulisayo ezakhiwei-heterodimeric(ezimbili ezihlukene) izinhlobo zesakhiwo, igama elisemthethweni le-molecule ewumphumela lithii-exciplex. Ama-exciplexes e-Krypton-chloride (KrCl) ayafiseleka ngokukhipha kwawo ama-photon e-ultraviolet angu-222 nm. I-wavelength engu-222 nm yaziwa ngamakhono ayo okulwa nokubulala amagciwane.
Kuyavunywa ngokujwayelekile ukuthi igama elithi excimer lingasetshenziswa ukuchaza ukwakheka kwakho kokubili imisebe ye-excimer kanye ne-exciplex, futhi idale leli gama.excilampuma ukhuluma ngama-excimer emitters asekelwe ekukhishweni.
