摘要

在室温下，通过60 kevx射线辐照，实验研究了纯氧化钇纳米粉末和陶瓷在250 ~ 750 nm的放射发光特性。在不同温度(1300 ~ 1500℃)的空气气氛中烧结陶瓷。重点研究了粉末压实和烧结温度对发光光谱的影响。结果表明，光谱具有相同的结构，由1个250 ~ 450 nm的宽带和4个系列的窄带组成。某些系列的起源被确定了。

Luminescence of Pure Y2O3 Nano-powder and Ceramics Exposed to X-ray Irradiation

250-750 nm radio luminescence of pure yttrium oxide nano-powder and ceramics was experimentally studied by exposing to 60 keVX-ray irradiation at room temperature. The ceramics were sintered in air atmosphere at different temperatures $1300-1500^{\circ}C$. We focused attention on the influence of powder compaction and sintering temperature on the luminescence spectra. It was showed that the spectra had an identical structure and consisted of one broad band 250-450 nm and 4 series of narrow bands. The origin of some series was identified.
