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, idatuluka m'gulu la sayansi ndipo idakhala 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 kutulutsa kwa ma photon a UV pamtunda wa 172 nm, womwe umagwiritsidwa ntchito kwambiri m'makampani pazolinga zotsegula.
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 zopha 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.
