Embodiment 1
[0010] Embodiment 1: take calcium carbonate (CaCO 3 ) 3.5g, magnesium oxide (MgO) 0.4g, boric acid (H 3 BO 3 )21.6g, diamine hydrogen phosphate [(NH 4 ) 2 HPO 4 ]6.6g, lead oxide (PbO) 0.1g, dilanthanum trioxide (La 2 o 3 ) 0.81g, the above-mentioned raw materials were crushed separately to make the particle size <7μ, and then fully mixed, put it into an alumina crucible, put it into a box furnace and slowly raise the temperature to 900 ° C, keep the temperature for 2 hours, take out the crucible and cool it to room temperature, and then The material in the crucible is finely passed through a 200-mesh sieve, put into the crucible again and burned at 950°C for 1 hour, crushed to 320 mesh, and the finished product is obtained after sieving. The spectrum measured by the fluorescent powder ultraviolet analyzer is a band spectrum, and the peak value is λ=2850 Ȧ.
Embodiment 2
[0011] Embodiment 2: take by weighing strontium carbonate (SrCO 3 ) 10.35g, magnesium oxide (MgO) 0.4g, boric acid (H 3 BO 3 )21.6g, diamine hydrogen phosphate [(NH 4 ) 2 HPO 4 ]6.6g, lead oxide (PbO) 0.1g, dilanthanum trioxide (La 2 o 3 ) 0.81g, the preparation process is with example 1. The spectrum of this embodiment is still a band spectrum, but the spectrum is shifted to the long wave, the peak value is λ=2970 Ȧ, and the intensity is stronger than that of phosphate activated by calcium zinc thallium and gadolinium.
Embodiment 3
[0012] Embodiment 3: the dilanthanum trioxide (La 2 o 3 ) into an equivalent amount of samarium trioxide (Sm 2 o 3 ) or gadolinium trioxide (Gd 2 o 3 ), other raw materials and preparation process are with embodiment 1.
