摘　　要：建立了体积分数为 0 .2 %甲醇存在下 ,Brij3 0协同 β- CD不经除氧诱导 α-溴代萘发射强的室温磷光的分析方法 ,详细讨论了各种因素对光谱特性的影响 .实验表明 ,这是一均匀的乳状体系 ,发射光谱具有良好的精细结构( 497nm和 5 97nm ) ,体积分数为 2 %以下的甲醇对体系磷光影响不大 ,磷光强度不随放置时间变化 ,但却与环境温度之间存在很好的线性关系 :Ip=8.68× 10 51/ T- 2 .4× 10 3.Without deoxygenation,strong room-temperature phosphoresecence(RTP) of α-Bromonaphthale- ne was induced synergetically by Brij30 and β-CD in the Volume ratio of 0.2 % methanol.The effect of various experimental conditions on the emission spectrum was studied in detail.The results showed this is an emulsion system and maximum emission wavelengths are at 497 nm and 527 nm.Less than Volume ratio 2 % methanol and incubation time hardly influence RTP.However,an excellent linear relationship(Ip= 8.68×10+51/T-2.4×10+3) was found between RTP intensity and temperature.
