The average size of nanocrystallites was controlled by different sintering temperatures. The structure and morphology of obtained nanopowders were examined using the XRD and SEM analyses. The Cr:Al2O3 was mixed with Tb3+:Y2O3 powders and its normalized emission was used to measure a relative intensity of Tb3+:Y2O3. The mixtures were electrophoretically deposited on ITO-glass slides. The cathodoluminescence spectra of obtained layers were recorded and analysed. The discussion over an influence of average grains size on phosphor efficiency was presented. 关键词：铽掺杂纳米晶阴极掺钇 X射线衍射分析 ITO导电玻璃性能粉体合成
