用日立MPF—4型荧光分光光度计及其磷光附件测定了磷光邮票的磷光带的磷光特性及强度。在磷光附件中使用了适当的装置以代替原有的杜瓦氏瓶。试验是在室温下进行。曾测验过8个不同国家的邮票上的磷光带。结果表明:中国邮票上的磷光带的发射顶峰波长范围是在460nm至467nm(蓝色光)。亦讨论了湿度对邮票磷光带的磷光强度的影响。
The phosphorescence characteristics and intensity of the phosphorescent bands of phosphorescent stamps were measured using a Hitachi MPF-4 fluorescence spectrophotometer and its phosphorescent accessory. Appropriate devices were used in the phosphorescent attachment to replace the original Duwar bottle. The test was conducted at room temperature. The phosphor bands on the stamps of 8 different countries have been tested. The results showed that the emission peak wavelength of the phosphor band on the Chinese stamp is in the range of 460 to 467 nm (blue light). The effect of humidity on the phosphorescence intensity of phosphor bands in stamps was also discussed.
