| 摘 要： | 本文首次采用高压方法合成了Sr3B2O6:Eu2+、Sr2B2O5:Eu2+、SrB4O7:Eu2+一系列硼酸盐，研究了它们和SrB2O4:Eu2+的常压与高压合成产物的发光光谱、强度及效率的变化，以及发光与其结构的关系。由于硼酸盐在高压处理后，结构发生变化，因而光谱及发光强度均有所改变。尤其对SrB2O4:Eu2+，在适当的合成压力条件及一定的激光条件下，其量子发光效率比常压提高80倍以上。

| Abstract: | Sr3BA6:Eu2+, Sr2B2O5:Eu2+ and SrB4O7:Eu2+ were synthesized by the high-pressure meihod for the first time,and luminescence measurements of them and SrB2O4:Eu2+ were carried out. The luminescence characters were compared with those under atmosphere. The structures and emission bands of Sr3B2O6:Eu2+ and Sr2B2O5:Eu2+ have been changed due to the high pressure processing. Under an appropriate pressure(2.8GPa)the emission intensity of SrB2O4:Eu2+ drastically increased. Its quantum efficency at the optinium excitation 313nm is above 80 times higher than the previous one. |
