摘　　要：根据 Ｈｏ掺杂的氟氧化物玻璃陶瓷的吸收光谱，用 Ｊｕｄｄ－Ｏｆｅｌｔ理论计算了强度参量，并由此计算了激发能级的自发辐射跃迁速率、辐射寿命、荧光分支比和积分发射截面等光谱参量．Optical-absorption spectrum of Ho3+ ions in oxyfluoride glass ceramic was measured, from which the measured oscillator strengths were obtained. The Judd-Ofelt intensity param- etersΩ( = 2,4,6) were determined by a best fit of the calculated and measured oscillator strengths, the rms deviation was 3.5 ×10-7. Some predicted spectroscopic parameters of the ex- cited states, like the spontaneous radiative transition rate, radiative lifetime, branching ratio and integrated emission cross section were given using the intensity parameters. The spectroscopic parameters were comparable with some laser materials, and some of them were better.
