Eu3+-doped Na2Ti6O13 (Na2Ti6O13:Eu) nanorods with diameters of 30 nm and lengths 400 nm were synthesized by hydrothermal and heat treatment methods. Raman spectra at ambient conditions indicated a pure monoclinic phase (space group C2/m) of the nanor

Nanocrystal samples (particle size about 90 nm) of Eu3+-doped rutile titanium dioxide (TiO2) nanocrystals (rutile Eu3+/TiO2 nanocrystals) were synthesized by the sol–gel method with hydrothermal treatment. The pressure effect on photoluminescence (

The influence of Eu3+ on the upconversion (UC) fluorescence of Er3+ in Y 2O3:Er3+, Y b3+ nanocrystals was investigated. Room-temperature UC spectra show that the intensity ratio of red to green lights was increased from 8.6 to 19.3 with 1.0 mol% Eu3+

Eu(OH)3 rods, with diameters of 140 nm and lengths of 100−500 nm were prepared by a hydrothermal method. X-ray diffraction indicated a pure hexagonal phase (space group P63/m) of the rods. The relations between structural and optical properties of
