| 摘 要： | 用相共轭配置的非相干光时间延迟四波混频技术测量了甲醇中甲酚紫的皮秒布居弛豫时间T1大约为157ps.这个结果与用相干光锁模脉冲的泵浦-探测技术测得的结果符合得比较好.

| Abstract: | Na5 Eu(WO4)4 is a good stoichimetric host luminescent material.The light emission eomes from high concentration host ions Eu3+.The effects of hydropressure on fluorescence of Eu3+ in Na5 Eu(WO4)4 have been invistigated under 0-80kbar at room temperature using a diamond anvil high pressure microspeetroscopic system.According to crystal field theory,the crystal parameter formulars of energy levels of Eu3+(in approximatary D2d point group symmetary site)are determind and fit with the experimental data of energy levels under high pressure.Then the ratios of crystal parameter variation Bkq(kq=20、40、44、60 and 64)to pressure variation ΔP are calculated. |
