Abstract
Mixed oxides activated by lanthanide ions can be excited via photons or high energy radiation (X and g-rays), so they are considered as promising phosphors and scintillators due to efficient light emission. In this project we aim to prepare three mixed oxides, namely gadolinium and aluminum oxide (GdAlO3), yttrium and aluminum oxide (Y3Al5O12), and yttrium and vanadium oxide (YVO4) by mea…
