Compared to the sorbet technique, our new technique toprepare glass–ceramics with persistent luminescence proper-ties using the melting process has the advantage of beingable to produce glass–ceramics with MPs, the compositionof which does not depend on the glass matrix compositionwhile the Frozen sorbet method can only be used for theprocessing of SrAl2O4:Eu2+,Dy3+glass–ceramics within theSrO Al2O3B2O3glass system.10,11However, compared to theFrozen sorbet method, our first glass–ceramics do not exhibithomogeneous luminescence due to an uneven MP distributionin the glass. The preparation of glasses with homogeneouslydistributed MPs is ongoing.
