| Popis: |
The fluorescent substances, (Zn_Mn_x)_ 2SiO_4 have been prepared at 1400℃ according to the solid-state reaction for x values between 0 and 1. The heating product between x=0 and 0.285 is a single phase of willemite. β-willemite phase was formed between x=0.290 and x=0.900. Tephroite phase was formed at x≩0.600. The heating product between x=0 and 0.285 emitted a green fluorescence(λ=520～525 nm) under ultraviolet light(λ=281.6 nm) excitation. A yellow fluorescence was emitted from the heating products between x=0.290 and x=0.800. Accordingly it has been concluded that willemite and β-willemite replaced by Mn were green and yellow fluorescent substances respectively. |
