    • Pleochroic fluorescent dyes of general formula (I), in which R is hydrogen or an aliphatic hydrocarbon radical containing not more than 20 carbon atoms and -CH2- between carbon atoms or adjacent to the bicyclo[2.2.2]octane residue may be replaced by -O-, may be dissolved in liquid crystal host material to form displays which are caused to fluoresce by incident low-energy ultraviolet initially absorbed by the liquid crystal host material and then internally transferred to the fluorophor. These dyes have greater stability to ultraviolet than other perylenedicarboxylic diesters while possessing good fluorescent properties and satisfactory order parameters. In formula (I), R is preferably a straight or branched alkyl and/or cycloalkyl group having 3 to 10 carbon atoms, preferably 5 to 7 carbon atoms. The liquid crystal host material preferably contains an energy-transfer agent such as a 4-substituted 4''-cyanoterphenyl. The 4-pentyl- and 4-propyl- bicyclo[2.2.2]oct-1-yl perylenedicarboxylates of formula I and solutions of these dyes in nematic liquid crystal host "E7" (a mixture based on cyanobiphenyls containing 8% 4-pentyl-4"-cyanoterphenyl) are described in examples.

    • A radiation meter for measuring the intensity of incident UV radiation in a predetermined wavelength band against a background of broadband radiation (24), such as sunlight, includes a sheet (3) of a material incorporating a fluorescent dye. The dye is selected to absorb radiation in the predetermined wavelength band and consequently to emit fluorescent radiation. The fluorescent radiation is internally reflected within the sheet and emerges from an edge of the sheet, where it impinges on a photodiode (9). The photodiode produces an output which is dependent upon the intensity of the UV radiation. This output is used to drive a suitable display. The unwanted background radiation passes through the sheet without causing fluorescence of the dye, and is absorbed in an absorbant backing layer (7). The photodiode is so positioned and screened that the background radiation cannot impinge upon it. A particularly advantageous use of the meter is for measurement of the intensity of UVB radiation, which is the cause of sunburn and skin cancer.
    • 用于测量相对于诸如太阳光的宽带辐射(24)的背景的预定波长带入射的紫外线辐射的强度的辐射计包括包含荧光染料的材料的片材(3)。 选择染料以吸收预定波长带中的辐射,并因此发射荧光辐射。 荧光辐射在片材内部被反射并从片材的边缘出射,在其边缘处照射在光电二极管(9)上。 光电二极管产生的输出取决于UV辐射的强度。 该输出用于驱动合适的显示。 不需要的背景辐射穿过片材而不引起染料的荧光,并被吸收在吸收背衬层(7)中。 光电二极管如此定位和屏蔽,使得背景辐射不会撞击它。 仪表的特别有利的用途是测量UVB辐射的强度,UVB辐射是晒伤和皮肤癌的原因。
