Subsequently, the mixture was dried in a drying oven at 10 (r under rc). The dried mixture was then subjected to 1000 in a CO atmosphere. (: Annealing in the lower aluminum crucible. Finally, the obtained powder cake was again compacted and in the air 1 〇〇 (2 hours under rc. Figure 1 shows the reflectance spectrum of PrzMhOn. From the spectrum of the graph, it shows that the compound has a relatively narrow absorption band in the region of about 570-580 nm and is at 510-540 nm. There is almost no absorption in the region, which makes the compound a good green filter, light sheet material. Without being bound by any theory, the inventors believe that these surprising features of the compounds of the invention are due, at least in part, to the host lattice and The relatively high covalent nature of the activator-oxygen bond. This can then create a covalent interaction between the cation and the anion' resulting in a partial relaxation of the quantum mechanical selection rule. Thus, the probability of transition of the 4f-4f transition increases and is individual The color of the pigment is more saturated.
