A combination of powder X-ray diffraction and neutron scattering technique was employed to explore the crystal structural evolution and the rigid nature from oxy- to oxynitride-based apatites, and some local structures were also characterized by HRTEM and\u00a029Si NMR data, respectively. The new La5(Si2+<i>x<\/i>B1\u2013<i>x<\/i>)(O13\u2013<i>x<\/i>N<i>x<\/i>):Ce3+\u00a0solid solution phosphors gave continuously controlled emission from 421 nm [La5Si2BO13:Ce3+, end-member (<i>x<\/i>\u00a0= 0)] to 463 nm (La5Si3O12N:Ce3+, end-member (<i>x<\/i>\u00a0= 1)). Substitution of B3+\u00a0and O2\u2013\u00a0by Si4+\u00a0and N3\u2013\u00a0in La5(Si2+<i>x<\/i>B1\u2013<i>x<\/i>)(O13\u2013<i>x<\/i>N<i>x<\/i>):Ce3+\u00a0phosphors produced more covalency into the crystal field environment around the Ce3+\u00a0ions inducing the red-shifted emission, further improving the thermal stability of the oxynitride-based apatite phosphors. The proposed approach from oxy- to oxynitride based iso-structural phases could significantly contribute to future research in designing complex solid solution phosphors <a href='https:\/\/www.east-inflatables.co.za\/e106055-inflatable-bumper-ball.html' style=\"color: grey; text-decoration: none;\">bubble soccer cape town<\/a>.<\/p>\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>J.
