Description
Summary:A series of Na sub(2)O-CaO-SiO sub(2) glass ceramics containing different content of Nd super(3+) ions were prepared by the method of high temperature melting and subsequent crystallization. The absorption, excitation and emission spectra of these glass ceramics were investigated; effects of Nd super(3+) content and crystallization behavior on the laser properties of this material had been studied. The results show that the emission bands originating from the super(4)F sub(3/2) state of Nd super(3+) were firstly enhanced with the increase of the Nd sub(2)O sub(3) doping content and the crystallinity degree, and then decreased with more doping content and deepened crystallization. The possible reasons of this phenomenon were analyzed. Research will be favored to promote the development of glass ceramics laser materials for space solar energy.
