TI  - Solid-state fluorescence study of naphthalene adsorption on porous material.
PG  - 239-43
AB  - Naphthalene adsorption profile on porous materials was studied using solid-state 
      fluorescence spectroscopy. When naphthalene crystals were simply mixed with 
      porous crystalline cellulose (PCC), excimer emission of naphthalene was observed 
      after 1 min of mixing, suggesting a drastic change in the naphthalene molecular 
      environment during the mixing procedure. For the naphthalene-octadesyl silane 
      (ODS)-80A or naphthalene-ODS-2 systems, the changes in adsorption profiles and 
      fluorescence spectral pattern of naphthalene were similar to those of the 
      naphthalene-PCC system. The final amounts of naphthalene adsorbed to ODS-80A and 
      ODS-2 were 0.05 and 0.024 g/g adsorbent, respectively, even though the two 
      materials had comparable values of specific surface area. The relative emission 
      intensity (I(excimer)/I(monomer)) in the ODS-80A system was higher than that in 
      the ODS-2 system when compared at the same amount of naphthalene adsorbed. It was 
      concluded that the pore size of porous materials affected the naphthalene excimer 
      formation on the surface.
