چکیده

Highly emitting 8-propargylaminoBODIPY (8-PAB) 2 was prepared in 94% yield. Unlike any other BODIPY structure hitherto described in the literature, 2 displays efficient emission in the blue region of the visible spectrum with a fluorescence quantum yield up to 0.94 and high laser efficiency (35%) at 483 nm.

Lifetime, Efficiency and Photostability Enhancement of Pyrromethene Laser Dyes by Metallic Ag Nanoparticles

Complexation of metallic silver nano particles (NPs) with Pyrromethene laser dyes (PM567, PM597) has significant effect on lifetime, photostability and the fluorescence efficiency. These enhancement of optical properties of the complex in solution due to surface Plasmon resonance (SPR) have been promised higher efficiencies in case of [40% Ag NPs: PM dye] complexes for dye laser systems. The fl...

Highly photostable solid-state dye lasers based on silicon-modified organic matrices

We report on the synthesis, characterization, and physical properties of modified polymeric matrices incorporating silicon atoms in their structure and doped with laser dyes. When the silicon-modified organic matrices incorporated pyrromethene 567 PM567 and pyrromethene 597 PM597 dyes as actual solid solutions, highly photostable laser operation with reasonable, nonoptimized efficiencies was ob...

Novel pyrromethene dyes with N-ethyl carbazole at the meso position: a comprehensive photophysical, lasing, photostability and TD-DFT study.

Two novel BODIPY (pyrromethene, PM) dyes containing N-ethyl carbazole at the meso position are synthesized and their photophysical properties in different solvents and the photochemical stabilities and laser performances in n-heptane are investigated. The n-heptane solution of the dyes was used as a gain medium in a constructed narrow band dye laser, pumped by a Q-switched (10 Hz) frequency-dou...

Photophysical and laser emission studies of 8-polyphenylene-substituted BODIPY dyes in liquid solution and in solid polymeric matrices.

In our search for efficient and photostable laser dyes, four new dyes with the basic structure of the commercial BODIPY laser dye PM567, with either an 8-diphenylene or an 8-p-triphenylene group, both substituted at the terminal polyphenylene position with an acetoxymethyl (dyes P2Ar1Ac and P3Ar1Ac, respectively) or a methacryloyloxymethyl group (dyes P2Ar1MA and P3Ar1MA, respectively), have be...

Characteristics of a broadband dye laser using Pyrromethene and Rhodamine dyes.

A broadband dye laser pumped by a frequency-doubled Nd:YAG laser with a full width at half-maximum from 592 to 610 nm was created for the use in a dual-pump broadband coherent anti-Stokes Raman spectroscopy (CARS) system called width increased dual-pump enhanced CARS (WIDECARS). The desired broadband dye laser was generated with a mixture of Pyrromethene dyes as an oscillator gain medium and a ...
