Embodiment 1
[0057] This example relates to the preparation of matrix glass.
[0058] The first step: according to the matrix glass formula:
[0059] 1.3171SiO 2 -3.4156B 2 o 3 –0.8940Al 2 o 3 -10.8067Gd 2 o 3 -0.1509CeO 2 , after fully mixing the components uniformly, melt in the air atmosphere at 1500°C for 2 hours by melting method;
[0060] Step 2: Pour the above melt into a preheated 600°C stainless steel mold for casting, and cool naturally to form glass; and
[0061] Step 3: Put the above glass in a muffle furnace at 600° C. for 4 hours and heat it for 4 hours for annealing treatment to obtain the scintillation glass according to Example 1.
[0062] Optical photographs of the scintillation glass according to Example 1 were taken by means of a digital camera.
[0063] The X-ray excitation emission spectrum of the obtained scintillation glass was tested with an X-ray excitation emission spectrometer (FLS980, Cu target, 30kV, 3mA).
[0064] Optical photograph of the scintill...
Embodiment 2
[0067] This example involves the partial substitution of Al with AlN 2 o 3 To prepare a colorless transparent cerium-activated borosilicate scintillation glass according to the present application.
[0068] The preparation process of the scintillation glass of the present embodiment is the same as that of Example 1, but the glass formula is as follows:
[0069] 1.4256SiO2 2 -3.5211B 2 o 3 -1.1612Al 2 o 3 -0.2334AlN-9.9772Gd 2 o 3 -0.1634C eO 2 , and finally the scintillation glass according to Example 2 was obtained.
[0070] The optical photograph and X-ray excitation emission spectrum of the scintillation glass according to Example 2 were measured by the same condition method as in Example 1. The test results are shown in figure 1 and figure 2 middle. The broad emission peak of the scintillation glass in Example 2 is around 405nm, indicating that AlN replaces part of Al 2 o 3 Ce in rear glass 3+ The concentration of ions increases, while the Ce 4+ As the io...
Embodiment 3
[0072] This example involves using BN to partially replace B 2 o 3 To prepare a colorless transparent cerium-activated borosilicate scintillation glass according to the present application.
[0073] The preparation process of the scintillation glass of the present embodiment is the same as that of Example 1, but the glass formula is as follows:
[0074] 1.3171SiO 2 -1.9924B 2 o 3 -0.5712BN-0.8940Al 2 o 3 -10.8067Gd 2 o 3 -0.1509C eO 2 , and finally the scintillation glass according to Example 3 was obtained.
[0075] The optical photograph and X-ray excitation emission spectrum of the scintillation glass according to Example 3 were measured by the same condition method as in Example 1. The test results are shown in figure 1 and Figure 4 middle. The emission broad peak of the scintillation glass in Example 3 is near 405nm, indicating that BN is used to partially replace B 2 o 3 Ce in rear glass 3+ The concentration of ions increases, while the Ce4+ As the ion c...
