By heating the amorphous film obtained by spin-coating method, crystallization took place at ca. 130 oC followed by melting and/or resolution to recover the homogeneous film over 200 oC. Both crystalline and amorphous phases could be reversibly obtained at room temperature by annealing the film at 130 oC and 245 oC, respectively. Such phase transition to control the state of the film at room temperature allowed the reversible fluorescence color change of the film due to the difference of emission spectra between amorphous and crystalline phases.}, pages = {559--562}, title = {Emitting Behaviors of 1-Acetylaminopyrene Dispersed in Poly(vinyl acetate) Film}, volume = {31}, year = {2018}, yomi = {タカハシ, ヒロキ and ナカノ, ヒデユキ} }
