Abstract The absorption and fluorescence of three isomeric distyrylbenzenes are investigated as function of temperature. From the fluorescence decay times and fluorescence quantum yields two classes of oligostyrylarenes can be distinguished. A decisive criterion for this classification is, whether the first excited singlet state S1 belongs to an allowed or forbidden transition S0→S1.

The partitioning of rare earth ions (REs: Yb3+, Er3+, Eu3+ and Nd3+) in γ-Ga2O3 nanocrystals (NCs) precipitated in a nanostructured silicate glass ceramic is revealed, and the enrichment of REs in the NCs (bulk doping) rather than on the interfaces between the NCs and the surrounding glassy phase (surface doping) is differentiated.

The absorption spectra of the 3 isomeric aza- and the 4 isomeric azinium-anthracenes are discussed on the basis of the absorption anisotropy, the oscillator strenght and the fluorescence decay times. The influence of endocyclic substitution depends on the position of the aza- and aziniumgroup, respectively. In the case of acridine, acridinium, benzo[g]quinolinium and benzo[f]- isoquinolinium the S0 → S2-transition is observable. The spectra of benzo[g]quinoline, benzo[f]- isoquinoline and acridizinium are similar to those of anthracene
