Paper Abstract

2-(2'-hydroxy-5'-methylphenyl)-5-chlorobenzotriazole (TINCl) compound belongs to class of compounds in which after UV excitation intra-molecular proton transfer reaction takes place in solid state at room temperature. Newly created proton- transferred form flouresces in the red range of the spectrum. Microscopic study of micrometer size flourescing crystals gives an opportunity to observe guiding and amplification of spontaneously emitted light. Maximum of light traveling along the crystal is shifted towards high-energy range. We called this transfer in needle of spontaneously emitted luminescence as TINSEL effect. Taking into account the total internal reflection phenomenon, qualitative explanation of TINSEL effect was done. TINSEL gives new possibility of application TINCl as homogeneous core fiber.
