Mawu akuti excimer amatanthauza mkhalidwe wanthawi yochepa wa atomiki momwe maatomu amphamvu kwambiri amapanga maatomu anthawi yayitali, kapenadimers, pamene anasangalala pakompyuta. Mawiri awa amatchedwaokondwa dimers. Pamene ma dimer okondwawo akubwerera ku chikhalidwe chawo choyambirira, mphamvu yotsalirayo imatulutsidwa ngati photon ya ultraviolet C (UVC).
M'zaka za m'ma 1960, portmanteau yatsopano,excimer, adatuluka m'gulu la sayansi ndipo adakhala mawu ovomerezeka kufotokoza ma dimer okondwa.
Mwa kutanthauzira, mawu akuti excimer amangotanthauzama homodimeric bondspakati pa mamolekyu amtundu womwewo. Mwachitsanzo, mu nyali ya xenon (Xe) excimer, ma atomu a Xe amphamvu kwambiri amapanga ma Xe2 dimers okondwa. Ma dimers awa amabweretsa kutulutsidwa kwa ma photon a UV pamtunda wa 172 nm, omwe amagwiritsidwa ntchito kwambiri m'makampani kuti ayambitse ntchito.
Pankhani ya chisangalalo complexes anapangaheterodimeric(awiri osiyana) structural mitundu, mawu ovomerezeka chifukwa molekyulu ndiexciplex. Krypton-chloride (KrCl) exciplexes ndi zofunika kuti atulutse 222 nm ultraviolet photons. Kutalika kwa 222 nm kumadziwika chifukwa champhamvu zake zothana ndi tizilombo toyambitsa matenda.
Nthawi zambiri amavomereza kuti mawu akuti excimer atha kugwiritsidwa ntchito kutanthauza kupangidwa kwa ma radiation a excimer ndi exciplex, ndipo apangitsa kuti mawuwa atchulidwe.excilampponena za zotulutsa zotulutsa zotulutsa zotulutsa.
