Igama elithi excimer libhekisa kwimeko ye-atomic yexeshana apho ii-athomu ezinamandla aphezulu zenza ii-molecular pairs ezihlala ixesha elifutshane, okanyeiidimers, xa zivuselelwa nge-elektroniki. Ezi zibini zibizwa ngokubaii-dimers ezichwayitileyoNjengoko ii-dimers ezivuselelwe zibuyela kwimeko yazo yokuqala, amandla aseleyo akhutshwa njenge-ultraviolet C (UVC) photon.
Ngeminyaka yoo-1960, i-portmanteau entsha,umhloli, yavela kuluntu lwesayensi yaza yaba ligama elamkelekileyo lokuchaza ii-dimers ezichwayitileyo.
Ngokwenkcazo, igama elithi excimer libhekisa kuphela kwiiibhondi ze-homodimericphakathi kweemolekyuli zohlobo olufanayo. Umzekelo, kwisibane se-xenon (Xe) excimer, ii-athomu ze-Xe ezinamandla aphezulu zenza ii-dimers ze-Xe2 ezivuselelweyo. Ezi dimers ziphumela ekukhutshweni kwee-photons ze-UV kubude be-172 nm, esetyenziswa kakhulu kushishino ngeenjongo zokuvula umphezulu.
Kwimeko yee-complexes ezivuselelweyo ezenziwei-heterodimeric(ezimbini ezahlukeneyo) iintlobo zesakhiwo, igama elisemthethweni lemolekyuli ephumayo lelii-exciplexIi-exciplex ze-Krypton-chloride (KrCl) ziyafuneka ngenxa yokukhupha kwazo ii-photon ze-ultraviolet ezingama-222 nm. Ubude be-wavelength obungama-222 nm buyaziwa ngezakhono zazo ezibalaseleyo zokulwa nokubulala iintsholongwane kwiintsholongwane.
Kuyavunywa ngokubanzi ukuba igama elithi excimer lingasetyenziselwa ukuchaza ukwakheka kwe-excimer kunye ne-exciplex radiation, kwaye livelise eli gamai-excilampxa kubhekiselwa kwii-excimer emitters ezisebenzisa i-discharge-based.
