The present invention provides a photoluminescent material comprising a composition of: aL. bm. cAL. dSi. pP. O. :fR Formula (I) wherein L is selected from Na and/or K; M is a divalent metal selected from one or more of the group consisting of Sr, Ca, Mg and Ba; Al, Si, P and O represent their respective elements; R is selected from one or more rare earth element activators; and wherein the variables a, b, c, d, p and f are: 0.0<a<0.1 0.0<b<0.3 0.0<c<0.4 0.0<d<0.3 0.0<p<0.5 0.0<f<0.25, with the proviso that at least one of the variables d and p is, and at least one of the variables a and b is 0. There is also provided a method involving a sol-gel process of manufacturing the photoluminescent material comprising. There is also provided the use of said photoluminescent material in glass-like end products. |
