Abstract

Optical radiative parameters for multichannel visible transition emissions have been determined in Sm

-doped cadmium-aluminum-silicate (CAS) glass under the excitation of a violet light emitting diode (LED). For the derivation

the necessary fluorescence spectra were measured and calibrated in an integrating sphere

which was connected to a CCD detector with a 400 μm-core optical fiber. The spectral power distribution and luminous flux distribution of the sample under the violet LED excitation have been obtained. And the total radiant flux and total luminous flux for the entire visible region have been calculated to be 712 μW and 12.1 mlm

respectively. The radiant flux and luminous flux for the four visible emission bands of Sm

were derived to be 36 μW and 9.7 mlm

which occupied 5% and 80% of the whole. The total quantum yield of the visible fluorescence of Sm

is 2.3%. Investigations on absolute spectral parameters for multichannel visible transition emissions of Sm

in CAS glass provide a valuable reference for heavy metal silicate glass in developing efficient display and illumination devices.
