[Photoluminescence band and anti-Stokes emission of native collagen in the visible range of the spectrum]. / Polosa fotoliuminestsentsii i antistoksovo izluchenie nativnogo kollagena v vidimoi oblasti spectra.

Photoluminescence (PL) of collagen, phenylalanine and tyrosine has been experimentally studied in the range of 400-700 nm. Anti-Stokes emission was observed when PL was excited by visible light. Possible participation of an excimer in generation of PL was shown. It has been pointed out that phenylalanine chromophore plays a dominant role in fluorescence generation of collagen in the spectrum visible range.
