In this study, we examined Sr₂ZnGe₂O₇:x% Mn²⁺ (SZGO:x% Mn²⁺) phosphors, with Mn²⁺ concentrations ranging from 0 to 6 mol %, synthesized via a solution combustion method using <em>Camellia sinensis</em> (<em>C.S.</em>) extract as the fuel. Upon monitoring the 539 nm emission, the excitation spectrum of the SZGO:4 %Mn²⁺ phosphors revealed two distinct ultraviolet (UV) excitation bands. When exposed to UV light, the phosphor produces a brilliant green emission at 539 nm, which corresponds to the characteristic Mn²⁺ transition (⁴T₁→⁶A₁). Moreover, the SZGO:4% Mn²⁺ phosphor achieved an internal quantum efficiency (<em>I_QE</em>) of 86.57 % and maintained a thermal stability of 90.73 % at 420 K. Thermometric analysis reveals that SZGO:4% Mn²⁺ phosphors achieve a maximum relative sensitivity (<em>S_r</em>) of 0.2112 % <em>K</em>⁻¹ at 300 K. Ultimately, a high-performance w-LED is assembled by coating commercial blue and red phosphors with the SZGO:4% Mn²⁺ phosphors on a 310 nm UV chip, yielding a correlated colour temperature (CCT) of 5391 K and an impressive colour rendering index (CRI) <em>R_a</em> of 93.7. In addition, the aging, thermal and continuous operation tests are conducted on w-LEDs to evaluate the stability of the devices. The results show that the phosphor can improve the operational stability of w-LEDs. These findings underscore the potential of SZGO:Mn²⁺ as an effective green component in w-LED lighting applications. Additionally, the outstanding luminescence properties of SZGO:4% Mn²⁺ phosphors are further leveraged for anti-counterfeiting (AC) purposes, enabling multi-level security features under UV-254 nm excitation.

XPS spectra verify the coexistence of Ti³⁺/Ti⁴⁺ and Fe²⁺/Fe³⁺ pairs in this compound. The CCTFVO ceramics displayed pronounced frequency-dependent dielectric behaviour, and a relaxor-like dielectric response appeared between 173 K and 450 K. That was ascribed to the movement of double-ionized oxygen vacancies with thermal activation energy of 1.10 eV. At 100 kHz and 300 K, the CCTFVO ceramics had relative dielectric constant (<em>ε</em>_r) of ∼ 138 and dielectric loss (tan<em>δ</em>) of 0.56. A diffuse phase transition undergoes near 330 K under 1 kHz. The CCTFVO QPOs exhibit ferrimagnetism at 2 K with saturated magnetization of 1.11 <em>μ</em>_B/f.u. and magnetic <em>T</em>_C = 623 K. The Curie-Weiss fitting of the inverse magnetic susceptibility (<em>χ</em>^-1) versus temperature curve, yielded the positive <em>θ</em>_P value of 767 K, confirming the predominant ferromagnetic interactions in the CCTFVO powders.

Below ∼ 166 K the zero-field cooling (ZFC) and field-cooling (FC) curves became bifurcated each other, and the ZFC curve decreased further upon cooling. This phenomenon is attributed to the presence of short-range spin clusters in the ferromagnetic background. It can be ascribed to the partial disorder of B-site ions, leading to local random potentials and consequently resulting in local competition between the ferromagnetic state driven by double-exchange interactions and antiferromagnetic state driven by superexchange interactions.
