摘要：

The up-conversion of infrared radiation into blue, green and red fluorescences has been investigated for erbium-doped titanium dioxide (TiO2) optical planar waveguides. These waveguides have been prepared by a sol-gel process and a dip-coating technique. The lifetime measurements of the S-4(3/2) level (green fluorescence) were performed using a pulsed excimer-pumped dye laser operating at 650 nm, They were found to depend strongly on the Er3+ ion concentration.
