چکیده انگلیسی
Under the pumping of violet lighting emitting diode, quantum yields for multichannel transition emissions have been determined in Sm3+-doped heavy metal tellurite glass for the first time. For the derivation, the necessary fluorescence spectra were measured and calibrated in an integrating sphere connected to a CCD detector with a 400 μm-core optical fiber. The spectral power distribution of the sample was derived from the measured spectra first, and then the quantum yields of the visible emissions of Sm3+ were calculated based on the distribution. The total quantum yield for four emission transitions of Sm3+ in visible region is 4.07%. Integrating sphere with a CCD detector is proven to be a reliable and reproducible method to characterize luminescence and laser materials.
