Aerosol synthesis of TiO(2):Er(3+)/Yb(3+) submicron-sized spherical particles and upconversion optimization for application as anti-counterfeiting materials
Er(3+)/Yb(3+)-doped TiO(2) up-conversion (UC) phosphors were prepared by spray pyrolysis, and the UC luminescence properties were optimized by changing the calcination temperature and the concentration of Er(3+) and Yb(3+) dopants. TiO(2):Er(3+)/Yb(3+) showed green and red emissions due to the (2)H(...
