Low Threshold

A random laser was achieved in a polymer membrane with silver nanoflowers on a flexible substrate. The strong confinement of the polymer waveguide and the localized field enhancement of silver nanoflowers were essential for the low-threshold random lasing action. The lasing wavelength can be tuned by bending the flexible substrate. The solution phase synthesis of the silver nanoflowers enables easy realization of this type of random lasers. The flexible and high-efficiency random lasers provide favorable factors for the development of imaging and sensing devices.

The PTyr (O-phosphotyrosine) pentapeptide H-Asn-Glu-Tyr(PO3H2)-Thr-Ala-OH.HO2CCF3, which is a naturally occurring sequence from the autophosphorylated Rous sarcoma virus pp60V-SrC, was prepared in high yield by the use of Boc-Tyr(PO3Me2)-OH in the Boc mode of solution-phase peptide synthesis. The protected pentapeptide, Z-Asn-Glu(OBzl)-Tyr(PO3Me2)-Thr(Bzl)-Ala-OBzl, was deprotected by a two-stage procedure which involved initial palladium-catalysed hydrogenolysis followed by the removal of the phosphate methyl groups by the use of one of the following treatments: (A) 10% bromotrimethylsilane/acetonitrile, (B) 1 M bromotrimethylsilane/thioanisole in trifluoroacetic acid, or (C) trifluoromethanesulfonic acid/trifluoroacetic acid/dimethyl sulfide/m-cresol.
