The aim of this study was to investigate properties of ceramic phosphors fabricated using nano Lu3Al5O12:Ce3+ phosphors produced with a sol-gel-combustion method. These nano Lu3Al5O12:Ce3+ phosphors had a size of about 200 nm. leading to high density when fabricated as a ceramic phosphor. We manufactured ceramic phosphors through vacuum sintering. https://hollandscountryclothinges.shop/product-category/arm-guards/
