Enhanced 2.0 μm and visible up‐conversion emissions from Ho 3+ via Yb 3+ sensitization in lead silicate glasses have been obtained under the excitation of 980‐nm laser diode. The possible energy transfer mechanism has been analyzed based on the photoemission spectroscopy and lifetime measurement. The lifetime of Ho 3+ : 5 I 7 laser upper level has also been measured. Based on the absorption spectra, Judd–Ofelt parameters, spontaneous emission probability, the absorption, emission cross sections, and gain coefficients have been calculated and analyzed. The results indicate that the Yb 3+ /Ho 3+ co‐doped lead silicate glass has potential application in mid‐infrared wavelengths.
