Tin phosphate glass containing embedded luminescent material particles

摘要

The invention provides a tin phosphate glass containing embedded luminescent material particles, wherein the luminescent material particles comprise luminescent material from the class of CaAlSiN 3:Eu 2+ and optionally other luminescent material particles. The invention further provides a method for the production of such glass as well as a lighting unit using such glass as (part of) a light conversion unit.
