Abstract

In this paper, investigations of extra-long phosphorescence in organic materials and optical crystals at cryogenic temperatures are presented. This study continues the cycle of our previous works devoted to the physical mechanism understanding of the long-run phosphorescence excitation. We wish to create an advanced and efficient laser for the media based on the Shpolsky matrix analogue. Another goal is to consider the possibility of building an optical processor with an extra-long phosphorescence effect. For this purpose we were examining the experimental setup of complicated organic materials: cocamidopropyl betadine C19H38N2O3, polyethylene terephthalate (C10H8O4) n , perfluoro (2-methyl-3-pentanone, Novec 649) CF3CF2C(O)CF(CF3)2, Kalosha benzine (benzine BR-2, Nefras С2 80/120). Different optic and piezo crystals were also investigated: gadolinium aluminum gallium garnet Gd3Ga3Al2O12:Ce, lanthanum gallium silicate La3Ga5SiO14, terbium gallium garnet Tb3Ga5O12 , La3Ga5,5Ta0,5O14.
