Fluorescent glass ceramic with high transparency and preparation method and use thereof

A fluorescent glass ceramic with transparency, comprising the following raw materials by mass percentage:

• 63 wt % to 70 wt % of SiO2, 13 wt % to 16 wt % of Li2O, 1 wt % to 6 wt % of Al2O3, 1 wt % to 10 wt % of K2O, 2 wt % to 6 wt % of P2O5, 1.5 wt % to 3.0 wt % of CeO2, 1 wt % to 4 wt % of an additive, 1.5 wt % to 3.0 wt % of a lanthanide oxide with an atomic number of 59 to 71, and 1 wt % to 4 wt % of a colorant, wherein
• the fluorescent glass ceramic has a lithium metasilicate crystal as a principal crystalline phase;
• the lithium metasilicate crystal has a layered or plate-like structure;
• the lithium metasilicate crystal has a grain size of 0.1 μm to 1.5 μm;
• the additive comprising at least one selected from the group consisting of a monovalent metal oxide and a divalent metal oxide;
• and
• the raw materials for the fluorescent class ceramic do not comprise a pentavalent metal oxide and a hexavalent metal oxide.
