suggest that varying the mol% of Pb2+ions does not affect the crystal structure of the phosphor. The crystallites sizes were estimated by using the Scherrer formula [21], using the most intense peak, and were found to be 22, 29, 21, 30 and 22 nm for the 0, 0.25, 1, 3 and 5 ...
6.765 g/cm3 for the idealized formula. In polished section, sidpietersite is light grey in plane-polarized reflected light in air, with ubiquitous brilliant white to yellow-brown internal reflections; the phase is bireflectant and perhaps slightly pleochroic. Averaged results of electron-microprobe...
