The lower case is more difficult to detect. The simplest way to obtain the necessary information in this case is to use a thick region with dense filling of D2 dyes, so that the two D1 regions appear separated despite of the strong bending of the mean phase boundary. 18 shows fluorescence microscopy images of a bipolar three-dye antenna material with POPOP in the middle, followed by Pyþ and then by Oxþ. The different color regions that can be observed in this simple experiment are impressive. The red color of the luminescence (1) disappears, when the crystal is observed trough a polarizer parallel to the crystal axis while the blue emission disappears when turning the polarizer by 90 .

32). u. 25. Absorption and fluorescence spectra of Pyþ and Oxþ in zeolite L, measured in an aqueous dispersion. The different spectral overlap regions are shaded. by the extinction coefficient ej ð" v Þ of the acceptor as a function of the wave number v" (it is usually expressed in units of cm3/M). 25. It is difficult to measure the oscillator strengths of molecules embedded in a matrix. Despite this, good values of Jij can be determined as a function of the temperature. A procedure we have used to extract the information from excitation spectra was to set the maximum of the excitation spectrum measured at room temperature equal to the extinction coefficient at the absorption maximum in solution.
