Nano-porous SiO2-matrices for development of new optical materials
Keywords:
SiO2-matrice, organic phosphors, scintillation characteristics
Abstract
Nano-porous transparent SiO2-matrices obtained by sol-gel techniques and organic phosphors PPO, o-POPOP, p-Tр are produced, and their optical, luminescent, and scintillation characteristics are studied. It is shown that these simples generate an intense photoluminescence signal, possess a nanosecond decay time. The absolute light yield of the composites was determined to be 4400 photon/MeV for SiO2:PPO, 5100 photon/MeV for SiO2:o-POPOP, and 1800 photon/MeV for SiO2:pTh.
