Ce: YAG - Yakakosha Scintillation Crystal

Ce: YAG yakakosha scintillation crystal ine yakanakisa scintillation performance. Iyo ine yakanyanya kupenya inoshanda uye yakafara optical pulse. Mukana wakakura ndewekuti iyo yepakati wavelength ye luminescence i550nm, inogona kunyatsobatanidzwa nemidziyo yekuona senge silicon photodiodes. Kuenzaniswa neCsI scintillation crystal, Ce: YAG scintillation crystal ine kukurumidza kuora nguva, uye Ce: YAG scintillation crystal haina deliquescence, yakakwirira tembiricha kuramba, uye yakagadzikana thermodynamic performance. Inonyanya kushandiswa mukuonekwa kwechiedza chechiedza, alpha particle yekuona, gamma ray yekuona uye mamwe minda. Uye zvakare, inogona zvakare kushandiswa mumagetsi ekuona kufungidzira (SEM), yakakwirira-resolution microscopic imaging fluorescent skrini uye mamwe minda. Nekuda kweiyo diki yekuparadzanisa coefficient yeCe ions muYAG matrix (inenge 0.1), zvakaoma kuisa maCe ions mumakristaro eYAG, uye kuoma kwekukura kwekristaro kunowedzera zvakanyanya nekuwedzera kwekristaro dhayamita.
Ce: YAG single crystal ndeye kukurumidza-kuora scintillation zvinhu zvine yakanakisa huchenjeri zvinhu, ine yakakwira mwenje kubuda (20000 photons/MeV), nekukurumidza kupenya kuora (~ 70ns), yakanakisa thermomechanical zvivakwa, uye inopenya peak wavelength (540nm) Zvakanaka. inofananidzwa neinogashira yewavelength yeyakajairwa photomultiplier chubhu (PMT) uye silicon photodiode (PD), yakanaka chiedza pulse inosiyanisa gamma rays uye alpha particles, Ce: YAG yakakodzera kuona alpha particles, maerekitironi uye beta rays, nezvimwewo. zvimiro zvezvimedu zvinochaja, kunyanya Ce: YAG imwe kristaro, inoita kuti zvikwanise kugadzirira mafirimu matete ane ukobvu hwepasi pe30um. Ce: YAG scintillation detectors anoshandiswa zvakanyanya muelectron microscopy, beta uye X-ray kuverenga, erekitironi uye X-ray imaging screens nemimwe minda.
