The authors synthesized three series of specimens: (1) Sr{sub 2.73-p}Ca{sub p}Ba{sub 0.2}Eu{sub 0.07}(PO{sub 4}){sub 2}{sm_bullet}BaCl{sub 2} series (the replacement of SrHPO{sub 4} by CaHPO{sub 4} in the charge); (2) Sr{sub 2.73-p}Ba{sub n}Eu{sub 0.07}(PO{sub 4}){sub 2}{sm_bullet}BaCl{sub 2} series (replacement of SrCO{sub 3} by BaCO{sub 3}); (3) Sr{sub 2.73}Ba{sub 0.2}Eu{sub 0.07}(PO{sub 4}){sub 2}{sm_bullet}(Ba{sub 1-w}Sr{sub w})Cl{sub 2} series (replacement of BaCl{sub 2} by SrCl{sub 2}). The authord showed that all the replacements greatly change the color coordinate y as compared with the coordinate x in the luminophor powder. Moreover, the replacement of SrHPO{sub 4} by CaHPO{sub 4} (up to the 1.0 mole/mole of basis) and of SrCO{sub 3} by BaCO{sub 3} leads to broadening of the long-wave portion of the luminophor radiation spectrum, to a decrease of the intensity of the maximum, while the replacement of BaCl{sub 2} by SrCl{sub 2} gives the opposite results.
