YAP:Ce Scintillator, Yap Ce Crystal, YAp:Ce Scintillation tioata

fa'amatalaga puupuu:

YAP:Ce ose tioata fa'asao vave fa'atasi ma le malosi fa'ainisinia lelei ma mea e fa'asa'o i kemikolo.O le malosi faʻainisinia maualuga e mafai ai ona faʻaogaina saʻo, faʻamalama ulufale e mafai ona faia i se mea sili ona manifinifi alumini e teu i luga o le tioata.

YAP:Ce scintillator o le isi tioata fa'afefeteina fa'apipi'iina i iona o le cerium (Ce).O le YAP o le yttrium orthoaluminate co-doped ma le praseodymium (Pr) ma le cerium (Ce).YAP:Ce scintillators e iai le malamalama maualuga ma le fa'ai'uga fa'aletino, e fa'atatau mo su'esu'ega fa'a-fisiki maualuga fa'apea fo'i su'e su'ega positron emission tomography (PET).

I su'esu'ega PET, o le YAP:Ce scintillator e fa'aoga tutusa ma le LSO:Ce scintillator.O le YAP:Ce tioata e mitiia ai ata o lo'o fa'aosoina e le radiotracer, ma fa'atupu ai le malamalama fa'alelei lea e iloa e se fa'alava photomultiplier (PMT).Ona fa'aliliuina lea e le PMT le fa'ailo fa'alelei i fa'amaumauga numera, lea e fa'agasolo e fa'atupuina ai se ata o le tufatufaina atu o le radiotracer.

YAP:Ce scintillators e sili atu nai lo LSO:Ce scintillators ona o lo latou vave tali atu, lea e fa'aleleia ai le fa'ai'uga fa'aletino a PET su'e.E iai fo'i a latou taimi fa'ato'a maualalo, fa'aitiitia ai a'afiaga o le fa'atupuina ma le taimi mate i mea tau eletise.Ae ui i lea, YAP:Ce scintillators e sili atu le taugata e gaosia ma itiiti ifo le mafiafia nai lo LSO:Ce scintillators, lea e a'afia ai le fa'afanua fa'afanua o PET su'e.

YAP:Ce scintillators e tele fa'aoga e ese mai lo latou fa'aogaina i su'ega PET ma su'esu'ega fa'atekinolosi maualuga.O nisi o nei talosaga e aofia ai:

1. Gamma-ray su'esu'eina: YAP:Ce scintillators e mafai ona iloa gamma-ave mai puna eseese, e aofia ai reactors faaniukilia, radioisotopes, ma meafaigaluega faafomai.

2. Mata'itūina fa'avevela: YAP:Ce scintillators e mafai ona fa'aoga e mata'ituina ai le maualuga ole fa'avevela ile fale eletise faaniukilia po'o nofoaga e a'afia i fa'alavelave faaniukilia.

3. Vailaau faaniukilia: YAP:Ce scintillators e mafai ona fa'aaogaina e fai ma su'esu'ega i metotia fa'ata e pei ole SPECT (Single Photon Emission Computed Tomography), e tutusa ma le PET ae fa'aaoga se isi radiotracer.

4. Saogalemu su'esu'e: YAP:Ce scintillators e mafai ona fa'aoga i su'esu'ega X-ray mo le siakiina o le saogalemu o atopa'u, afifi po'o tagata i malae va'alele po'o isi nofoaga maualuga saogalemu.

5. Astrophysics: YAP:Ce scintillators e mafai ona fa'aoga e iloa ai ave gamma o le lalolagi e fa'aosoina e puna fa'aletino e pei o supernovae po'o le gamma-ray pa.
