Figures & Tables

Figure 1

CL spectrum of synthetic zircon (SZ) after total instrumental correction operated at 0.1 nA in a scanning mode.

Figure 2

Deconvolution of the CL spectra in energy units obtained from SZ by using a Gaussian curve fitting. Measured spectrum shown by a black solid line; deconvoluted components by broken lines of blue one in the blue region and orange one in the yellow region; sum of the components by the red dotted line.

Figure 3

Color CL images of unimplanted (top) and He+ ion-implanted (bottom) SZ samples at 2.14×10–3 C/cm2.

Figure 4

CL spectra of unimplanted and He+ ion-implanted SZ samples at 2.23×10–5 C/cm2 to 2.14×10–3 C/cm2.

Figure 5

Spectral deconvolution of the CL spectra in energy units obtained from implanted samples at (a) He+ ion-implanted at 2.23×10–5 C/cm2 and (b) at 2.14×10–3 C/cm2 by using a Gaussian curve fitting. Measured spectrum shown by a black solid line; deconvoluted components by broken lines of blue one in the blue region and orange one in the yellow region; sum of the components by the red dotted line.

Figure 6

Spectral deconvolution of the CL spectra in energy units from Malawi zircon by using a Gaussian curve fitting. Measured spectrum shown by a black solid line; deconvoluted components by broken lines of green one for REE activations and orange one in the yellow region; sum of the components by the red dotted line.

Figure 7

A plot of integral CL intensities of emission components at (a) 1.96 eV, (b) 2.16 eV and (c) 3.26 eV against radiation dose (C/cm2) for unimplanted and He+ ion-implanted samples at 2.23×10–5 C/cm2 to 2.14×10–3 C/cm2.
