摘要

摘要采用溶胶-凝胶法制备了三价钆(Gd3+)掺杂的钙锌硅酸钙(Ca2ZnSi2O7/硬石岩)，其摩尔组成为Ca2−x ZnSi2O7:xGd3+ (x = 0.09 mol)。利用x射线衍射和傅里叶变换红外光谱对硬石岩进行了表征。x射线衍射研究表明，制备的样品含有Ca2ZnSi2O7的四方相。利用傅里叶变换红外光谱对样品的振动结构进行了研究。在273 nm激发下，Ca1.91ZnSi2O7:0.09Gd3+荧光粉窄带的光致发光发射光谱在312 nm处得到优化。电子顺磁共振研究证实了Ca1.91ZnSi2O7:0.09Gd3+基体中存在三价态钆离子。

Ultraviolet-B radiation from Gd (III) doped hardystonite

Abstract Trivalent gadolinium (Gd3+)-doped calcium zinc silicate (Ca2ZnSi2O7/hardystonite) with a molar composition of Ca2−x ZnSi2O7:xGd3+ (x = 0.09 mol) was produced using a sol–gel system. The hardystonite was characterized using X-ray diffraction and Fourier transform infrared spectroscopy. The X-ray diffraction study revealed that the prepared sample contained a tetragonal phase of Ca2ZnSi2O7. The vibrational structures of the sample were studied using Fourier transform infrared spectroscopy measurements. The photoluminescence emission spectrum of the Ca1.91ZnSi2O7:0.09Gd3+ phosphor narrow band was optimized at 312 nm in the Ultraviolet-B region under excitation at 273 nm wavelength. Electron paramagnetic resonance study authenticates the presence of gadolinium (Gd) ions within the trivalent state in the Ca1.91ZnSi2O7:0.09Gd3+ host.
