为了对存在于石英玻璃中的非桥氧空穴缺陷的特性进行研究,采用高频等离子体法对掺Yb
3+
石英玻璃进行了制备。首先介绍了玻璃样品的制备过程,然后对所制备的掺Yb
3+
石英玻璃样品的吸收特性、发射特性以及傅里叶变换红外吸收光谱进行了分析。结果表明,所制备的玻璃样品具有Yb
3+
离子典型的吸收特性。位于260 nm波长的吸收峰以及200 nm激发波长下产生的位于630 nm波长的发射峰都表明所制备的玻璃样品中存在非桥氧空穴缺陷。并且不同激发波长所产生的发射峰以及红外吸收光谱都说明玻璃样品中的非桥氧空穴缺陷是由Si-O和Si-OH-O-Si两类空穴中心构成,Yb
3+
离子对合作发光与非桥氧空穴缺陷间存在能量转移过程。
In order to study the characteristics of the non-bridging oxygen hole centers(NBOHC)defects in silica glass
Yb
3+
-doped silica glass was prepared using high frequency plasma technology. First of all
the preparation process of glass sample was introduced. The absorption characteristics
emission characteristics and Fourier transform infrared absorption spectra of the prepared Yb
3+
-doped silica glass were analyzed. The analysis results show that the prepared glass sample has the typical absorption pattern of Yb
3+
ion. The absorption peak at 260 nm and 200 nm-excited emission peak at 630 nm indicate that the NBOHC defects exist in the glass sample. What's more
both the emission peak generated by different exciting wavelengths and the infrared absorption spectra indicate that there are two kinds of NBOHC
in other words
Si-O and Si-OH-O-Si. The energy transfer process exists between cooperative emission of Yb
3+
ions pairs and NBOHC defects.
