BaBeF_4∶Sm^(3+)的温和水热合成与光谱性质研究

Studies on the Hydrothermal Synthesis and Spectral Properties of BaBeF 4∶Sm 3+

已报道的复合氟化物发光材料多数是通过高温固相反应或高温高压水热反应制备的［１～３］．高温固相合成方法需要苛刻的氟化设备，惰性气氛保护及高温（＞８００℃）条件．高温高压水热反应通常在４００℃以上进行，对反应设备要求高且反应不易控制．Ｓｍ３＋离子在不同基...

In this paper, we presented the hydrothermal synthesis of BaBeF 4∶Sm 3+ at a low temperature and studied the excitation and emission spectra of BaBeF 4∶Sm 3+ and emission intensities of Sm 3+ in BaBeF 4 as a function of Sm 3+ concentration.
