Abstract
Abstract A tin-phosphorous oxyfluoride glass in the Sn--P--O--F composition field is used as a supporting matrix for light-responsive polycyclic aromatic hydrocarbons, such as triplet state or lasing dyes. Dye compatibility with the glass is good, as evidenced by the fact that glasses containing the dyes exhibit luminescence characteristic of the dissolved dye in a rigid solvent.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
40 words
A tin-phosphorous oxyfluoride glass article containing at least one dissolved polycyclic aromatic hydrocarbon which exhibits a response to light or an electric field, the compound being present in a concentration ranging up to about 1% by weight of the glass.
Claim 2
Dependent Claim
40 words
A tin-phosphorous oxyfluoride glass article containing at least one dissolved polycyclic aromatic hydrocarbon which exhibits a response to light or an electric field, the compound being present in a concentration ranging up to about 1% by weight of the glass.
