Design, synthesis, crystal structure and luminescent properties of a new tantalum-phosphate K3BiTaP3O13 with negligible concentration quenching and good thermostability

This work reports a new host template, K₃BiTaP₃O₁₃, for both Eu³⁺ and Tb³⁺ luminescence, providing a ‘dimensional obstacle’ to suppress negative concentration quenching with a high density of Eu³⁺ or Tb³⁺.

Crystal structures, phase transitions and thermal expansion properties of NaZr2(PO4)3–SrZr4(PO4)6 solid solutions

Structures and phase transitions depending on compositions and temperature between R3̄c and R3̄ in Na_(2−2x)Sr_x[ ]_xZr₄(PO₄)₆ have been investigated.
