1 due to the glass structure becomes tight, the cubic phase of the -NaYF4 to the dense row of six square phase of the beta -NaYF4 transformation, the reason may be close to the six party NaYF4 crystal atoms arranged more closely, so that the precipitation of the crystal is suitable for the high degree of network connection in the glass matrix.
2 because of the increase of the crystallization temperature of the glass, the precipitation of beta -NaYF4 crystal is more favorable to the high temperature phase at higher temperature.
