Ce-doped yttria transparent polycrystalline ceramics with UV-shielding capability (IMAGE)
Caption
High optical quality Ce-doped Y2O3 transparent ceramics were fabricated. The introduction of Ce shifted the UV cutoff edge of Y2O3 transparent ceramics from 250 to 375 nm, which was attributed to the visible band absorption of Ce4+. This shift grants UV shielding capabilities to Y2O3 transparent ceramics. UV shielding capabilities of 5% samples against 254 nm and 305 nm radiation were evaluated using UV intensity indicator paper, which is known for its color transformation from white to purple upon UV light exposure.
