Product Description
CaF2:Eu is a scintillator crystal iyo inoburitsa chiedza kana ichinge yaratidzwa kune yakakwira-simba mwaranzi.Makristasi acho ane calcium fluoride ine cubic crystal chimiro uye europium ions inotsiviwa mune retice chimiro.Kuwedzerwa kweeuropium kunovandudza crystal's scintillation properties, zvichiita kuti inyatsoshanda pakushandura mwaranzi kuva chiedza.CaF2:Eu ine yakakwira density uye yakakwira nhamba yeatomu, iyo inoita kuti ive chinhu chakanakira kuona uye kuongorora gamma-ray.Pamusoro pezvo, ine simba rakanaka rekugadzirisa, zvichireva kuti inogona kusiyanisa pakati pemhando dzakasiyana dzemwaranzi zvichienderana nemazinga esimba ravo.CaF2:Eu inoshandiswa zvakanyanya mukufungidzira kwekurapa, fizikisi yenyukireya uye zvimwe zvikumbiro zvinoda kuongororwa kwemwaranzi yakanyanya.
CaF2:Eu scintillator crystals - nyaya dzinofanirwa kuziva: Nekuda kwekuderera kwayo uye kuderera Z, ine goho rakaderera kana ichidyidzana neakakwira simba gamma-rays.Iine bhendi yakapinza yekunyudza pa400nm iyo inodarika chikamu che scintillation emission band.
Performance Testing
[1]Emission spectrum:"emission_at_327nm_excitation_1" inoenderana nekuyera spectrum yechiedza chefluorescence chinoburitswa kubva mukristaro kana chafadzwa nechiedza pa 322 nm (ine 1.0 nm slitwidth pane tsime monochromator).
Iyo wavelength resolution yeiyo spectrum ndeye 0.5 nm (slitwidth yeanalyser).
[2]Excitation spectrum:"excitation_at_424nm_emission_1_mo1" inoenderana nekuyera fluorescence inoburitswa payakagadzika wavelength ye424 nm (0.5 nm slitwidth paanalyser) painenge ichitarisa kureba kwechiedza chinofadza (0.5 nm monochromatwidth).
Iyo photomultiplier (zviverengero pamasekonzi) yaishanda zvakanaka pazasi saturation saka zvikero zvakamira, kunyangwe zvisingaite, zvine mutsetse.
Kunyangwe iyo yebhuruu emission spectrum yeEu:CaF2 kubva kune vakasiyana vagadziri yakafanana, tinoona kuti excitation spectrum iri pakati pe240 ne440 nm inogona kusiyana zvakanyanya pakati pevagadziri vakasiyana:
mugadziri wega wega ane hunhu hwayo spectral siginecha / "fingerprint".Isu tinofungidzira kuti misiyano inoratidza akasiyana mazinga etsvina / kuremara / oxidation (valence) nyika
-Nekuda kwemamiriro akasiyana ekukura uye annealing yeEu: CaF2 crystal.
