Kedu ihe bụ excimer?

Okwu excimer na-ezo aka na ọnọdụ atọm nwa oge nke atọm ike dị elu na-etolite ụzọ abụọ molekul dị mkpụmkpụ, ma ọ bụdimers, mgbe eletrọnịkị obi ụtọ. A na-akpọ ụzọ abụọ ndị adimers nwere obi ụtọ. Ka dimers nwere obi ụtọ na-alaghachi na steeti mbụ ha, a na-ewepụta ike fọdụrụnụ dị ka ultraviolet C (UVC) photon.

Na 1960s, Portmanteau ọhụrụ,excimer, siri na obodo sayensị pụta wee bụrụ okwu anabatara maka ịkọwa dimers nwere obi ụtọ.

Site na nkọwapụta, okwu excimer na-ezo aka naanịnjikọ nke homodimericn'etiti ụmụ irighiri ihe nke otu ụdị. Dịka ọmụmaatụ, na oriọna excimer xenon (Xe), atom Xe nwere ike dị elu na-etolite Xe2 dimers nwere obi ụtọ. Ihe dimers ndị a na-ebute ntọhapụ nke foton UV na ogologo nm nke 172 nm, nke a na-ejikarị eme ihe na ụlọ ọrụ maka ebumnuche ịgbalite elu.

Krypton-chloride (KrCl) exciplexes bụ ihe a na-achọsi ike maka mpụta nke 222 nm ultraviolet photons. Ogologo ebili mmiri 222nm ka amara maka ikike mgbochi nje ya dị mma.
