The profile of optical imaging of the Gd2O3:Eu and 18F-FDG mixture. The contents in the Well 1–9 in this figure are listed as follows: Well 1: saline solution. Well 2: 18F-FDG. Well 3: Eu2O3 + 18F-FDG. Well 4: Gd2O3:Eu-50 + 18F-FDG. Well 5: Gd2O3:Eu-100 + 18F-FDG. Well 6: Gd2O3:Eu-200 + 18F-FDG. Well 7: Gd2O3:Eu-50@PVA + 18F-FDG. Well 8: Gd2O3:Eu-100@PVA + 18F-FDG. Well 9: Gd2O3:Eu-200@PVA + 18F-FDG. a optical imaging with an open filter. b the emission spectrum of contents in each well. c, d optical image (c), and quantification of the optical signal intensity (d) with 620 nm filter. e, f optical image (e), and quantification of the optical signal intensity (f) with 700 nm filter. g, h optical image (g), and quantification of the optical signal intensity (h) with swine intestine covered on the top
