Abstract: Aiming at exploring new phosphors with deep red or near infrared emission, Mn ion activated Ca₁₄Zn₆Al₁₀O₃₅ phosphor was synthesized using high-temperature solid-state method in the air. The spectra of X-ray diffraction curves, reflection spectra, photoluminescence spectra, as well as photoluminescence decay curves, of the phosphors were measured. Both deep red and near infrared emission from Mn⁴⁺ and Mn⁵⁺ ions respectively, were observed. The emission of Mn⁵⁺ ion reaches a maximum when Mn ions substitutes 12.5 % Al site in Ca₁₄Zn₆Al₁₀O₃₅. Mn⁵⁺ ion shows an intense narrow band emission centering at 1157 nm due to its ¹E→³A₂ transition, with the lifetime 87.46 ms in Ca₁₄Zn₆Al_8.75Mn_1.25O₃₅. The temperature sensitivity of the near infrared emission reaches a maximum 0.0024 K^–1 at 368 K. It is worth noticed that the energy transfer from Mn⁴⁺ to Mn⁵⁺ is observed, which extend the excitation band of Mn⁵⁺ widely and enable to excite the infrared emission of Mn⁵⁺ by the commercial InGaN blue chips. Moreover, the excitation and emission peaks locating at 650 nm and 1157 nm respectively are beneficial for real-time biological detection. Thus, we believe that the phosphor has great potential as a multi-functional infrared emission material.
