► The fluorescence excitation and emission spectra in MM possess a complex nature. ► Fluorescence decay kinetics for different degrees of polymerization of MM were investigated. ► The ICT fluorescence FWHM for EDMAADCy shows a linear dependence on the time of polymerization. ► EDMAADCy ...
摘要: The 4°K excitation spectrum of the 4 F 3/2‐4 I 11/2luminescence of Nd3+ in LaF3 was measured in the region of the six A absorption lines.关键词:Absorption spectra Luminescence DOI: 10.1063/1.1662373 被引量: 2 年份: 1973 收藏 ...
Energy transfer from Bi3+ to Tb3+ and Eu3+ is observed and the mechanism of energy transfer is investigated. Mechanism of energy transfer can be explained as electric multipole interaction since the Bi3+ emission band and Tb3+ or Eu3+ excitation band overlaps and the Bi3+ emission ...
