| 摘 要： | 在无任何保护性介质存在下,以Na2SO3作化学除氧剂,KI为重原子微扰剂,菲即能产生强而稳定的流体室温磷光发射.激光和发射波长λex/λem为283/482,504nm,不同有机溶剂存在对其磷光发射的性质有不同影响.1%乙腈存在时,菲浓度在8.0×10-7～6.0×10-6mol*L-1和6.0×10-6～4.0×10-5mol*L-1范围内分别与磷光发射强度呈良好的线性关系,检出限为2.6×10-8mol*L-1.

| Abstract: | A strong and stable room temperature phosphorescence (RTP) signal of phenanthrine aqueous solution in the absence of a protecting medium can be induced only by using Na2SO3 as deoxygenator and KI as heavy atom pertuber. The maximum phosphorescence intensity wavelengths are lambda ex/lambda em = 283/482,504 nm. It is also found that the kind and amount of organic solvent added to the luminescent system effects obviously the RTP properties. Under the present of 1% acetonitrile the RTP intensity is linear to phenanthrine concentration in the rage of 8.0 x 10(-7)-6.0 x 10(-6) mol.L-1 and 6.0 x 10(-6) mol.L(-1)-4.0 x 10(-5) mol.L-1, respectively. The detection limit is 2.6 x 10(-8) mol.L-1. |
