In the present study the various spectroscopic parameters of the triply ionized holmium (Ho³⁺) doped TeO₂–Pb₃O₄ (TPO) glass fabricated through melting and quenching technique have been investigated by using the Judd-Ofelt (J-O) analysis. The determined higher Judd-Ofelt intensity parameter Ω₂ signifies the existing covalent bonding. The transition ⁵S₂+⁵F₄→⁵I₈ corresponding to the peaked energy at 18552.9 cm⁻¹ shows the largest radiative transition probability (3315.5 s⁻¹) and gives the confirmation for the observed strong green emission in the Upconversion (UC) study. The UC spectroscopy of the Ho³⁺/Yb³⁺ ions doped and codoped TPO glasses upon 980 nm CW laser excitation have been analyzed. The effect on the UC luminescence intensity of Ho³⁺: TPO glass in the presence of Yb³⁺ ions has been studied and the intensity enhancement processes are explored. On the basis of present investigations, the Ho³⁺/Yb³⁺ codoped TPO glass can be utilized as good optical upconverter and yellowish green display devices.

在本研究中，通过使用 Judd-Ofelt (JO) 分析法研究了通过熔化和淬火技术制造的三重电离钬 (Ho ³⁺ ) 掺杂的 TeO ₂ –Pb ₃ O ₄ (TPO) 玻璃的各种光谱参数。确定的较高 Judd-Ofelt 强度参数 Ω ₂表示现有的共价键合。对应于 18552.9 cm ^-1处的峰值能量的跃迁⁵ S ₂ + ⁵ F ₄ → ⁵ I ₈显示出最大的辐射跃迁概率（3315.5 s ^-1) 并证实了上转换 (UC) 研究中观察到的强绿色发射。已分析了 Ho ³⁺ /Yb ³⁺离子掺杂和共掺杂 TPO 玻璃在 980 nm CW 激光激发下的 UC 光谱。已经研究了在 Yb ³⁺离子存在下对 Ho ³⁺ : TPO 玻璃的 UC 发光强度的影响，并探索了强度增强过程。根据目前的研究，Ho ³⁺ /Yb ³⁺共掺杂TPO玻璃可以作为良好的光学上变频器和黄绿色显示器件。
