description

Cinka oksīds ir plaši pētīts pusvadītājs ar lielu aizliegtās zonas platumu un lielu brīvo eksitonu saites enerģiju, tādejādi cinka oksīda eksitonu luminiscenci var novērot ne tikai pie zemas temperatūras, bet arī istabas temperatūrā. Savukārt ātrā eksitonu luminiscences dzišana nodrošina cinka oksīda potenciālu pielietojumu ātrdarbīgiem scintilatoriem. Darbā veikti trīs veidu cinka oksīdu pētījumi – monokristālisku, pulverveida un keramisku. Tika reģistrētas un salīdzinātas cinka oksīda luminiscentās īpašības, daļai paraugu pārbaudīta luminiscences spektru atkarība no temperatūras, luminiscences dzišana un paraugu homogenitāte. Apkopojot eksperimentālos rezultātus, novērtēts, kuri no pētītajiem materiāliem ir perspektīvākie scintilatoru izgatavošanai, tiek norādīts uz esošo materiālu priekšrocībām un trūkumiem
