The effect of WO4 group in xerogels doped with Ln2–xPrx(WO4)3 where Ln = La, Gd
photoluminescence praseodymium(III) ions sol–gel method energy transfer process
2011/5/6
We present a synthesis of highly efficient xerogels doped with Ln2–xPrx(WO4)3, where Ln = La
or Gd as novel phosphors. For comparison, the synthesis of xerogels doped only with Pr(III) and
La(III) i...
