Abstract: Y2O3:Eu3+ phosphor was deposited on quartz fibers by electron beam evaporation technology and the deposited fibers were then annealed at different rates from 1 to 10 °C/min. Particle shape of the Y2O3:Eu3+ deposited on fibers was changed with the increased annealing rate and the particle size was increased significantly with the rise of annealing rate to 5 °C/min. The deposited film on fibers exhibited a well cubic phase after annealing treatment and its crystallization was obviously enhanced with the increased rate. The luminescent properties of the films were markedly improved by annealing treatment and the emission intensity was increased as the rate elevated from 1 to 10 °C/min because of the increased radiative transition probability of the Eu3+ ions. The CIE chromaticity coordinates results indicated that the films can display improved color purity of red emission after annealing treatment and the color purity of the annealed films was gradually improved as the increased treating rate.
