Temperature and Pressure Measurements of PALS Spectra in Photonic Glasses

Abstract:

The subject of investigation was porous glass produced using a sol-gel technique. ortho-Ps lifetimes and intensities in the material were determined as a function of temperature and pressure. Temperature was ranged from 100 to 500 K while the pressure from 0 to 1200 MPa. Nitrogen gas intercalation into pore structure was observed up to 100 MPa.
