The invention discloses a rare-earth-ion-doped LiGdI4 microcrystalline glass and a preparation method thereof. The microcrystalline glass is composed of the following components in percentage by mole: 70-75 mol% of TeO2, 13-18 mol% of ZnF2, 10-11 mol% of LiGdI4 and 1-3 mol% of LnI3. The LnI3 is CeI3, EuI3 or TbI3. The preparation method comprises the following steps: preparing TeO2-ZnF2-LiGdI4-LnI3 glass by a fusion process, and carrying out heat treatment to obtain the transparent LiGdI4 microcrystalline glass. The LiGdI4 microcrystalline glass has the advantages of deliquescence resistance, favorable mechanical properties, higher short-wavelength blue-violet light transmission rate, strong light output, quick attenuation, favorable energy resolution, favorable time resolution and the like. The preparation method of the microcrystalline glass is simple and lower in production cost.
