【 摘 要 】

Rare earth based materials have recently attracted considerable attention as potential eco-friendly colourants for low temperature as well as high temperature applications. In the present study, we have synthesized a series of Ca-doped PrPO₄ compounds with the general formula, Pr_{1â€�?�ð�?��?}Ca_ð‘�?PO₄ (ð‘�? = 0â€�??0.4 in steps of 0.1) and characterized the compounds by powder X-ray diffraction. All the compositions show a monoclinic monazite structure. The optical properties of the brilliantly coloured pigments [𝐿 (brightness), $a^{ast}$ (+ red - green), $b^{ast}$ (+ yellow - blue)] have been examined. These materials can find application as potential green colourants.
