“…Materials based on aluminum oxide have a number of unique properties: mechanical strength, chemical stability, and thermal stability that make them suitable for the creation of various optical materials for quantum electronics and photonics. Moreover, anodized aluminum surface enhances luminescence of the rhodamine 6G dye by several times compared to porous glass [8]. The first experiments on lasing of organic compounds in anodized aluminum films obtained by sol-gel technology with adsorbed rhodamine dyes were performed in [9] under pumping by a pulsed N 2 laser with a pulse duration of 5 ns.…”

Spectral-luminescent and lasing characteristics of rhodamine 6G in porous aluminum oxide films anodized under various conditions are investigated. Lasing is obtained without external resonator in the longitudinal scheme under excitation by the second harmonic of Nd 3+ :YAG-laser radiation. The threshold pump power densities are in the range 3.5-15 MW/cm 2 depending on the anodizing conditions. Wherein, the lasing line narrows down from 12 to 5 nm.

“…At present, research concerning the creation of laser generation using nanostructured materials activated with organic laser dies is being actively carried out [4][5][6], in particular, with the use of aluminum oxide porous ceramics [7]. The studies of fluorescent properties of rhodamine dies incorporated into aluminum oxide pores were carried out in [8][9][10], where it was shown that the fluorescence intensity of rhodamine 6G dye in aluminum oxide matrix increased compared to that in porous glass. The induced emission in the geometry to transmission in a porous matrix of anodic aluminum oxide doped with rhodamine 6G was obtained in [11].…”

The generation of laser radiation by a nanostructured solid active element with natural selective optical nanoresonator formed in a nanoporous aluminum oxide film activated with rhodamine 6G has been obtained for the first time. The lasing is characterized by high-quality radiation with the absence of a spontaneous component. Chemical deposition of noble metals leads to the formation of internal nanoresonator into the porous structure. This reduces generation threshold more than two fold.

“…As a 3D tubular template, the PAA tubes' diameter and periodicity (centertocenter) can be con trolled by varying the anodizing conditions [19]. Because of the low cost and potential bioapplications, PAA has been used to fabricate enhanced substrates for PERS and PEF [20][21][22]. As shown in figures 1(c) and (d), the plasmonic AgNPs were deposited onto the PAA nanotube wall to enhance the fluo rescence of the molecules adsorbed on the wall, which can provide a particular distance between molecules and metal surface.…”

Three-dimensional (3D) plasmonic nanostructures of porous alumina array (PAA) with silver nanoparticles (AgNPs) were prepared for enhancing fluorescence emission. In order to avoid fluorescence quenching effects and obtain clear fluorescence enhancement, the molecules were separated by using such 3D substrates, and the mean distance between the molecules and nanoparticles' surface can be easily controlled by changing the diameters of the PAA tube. It was found that the PAA tube with smaller size provides better fluorescence enhancement. Enhanced cross section, a new fluorescence enhanced factor, combined with the simulation of localized electromagnetic field enhancement was presented to understand the experimental results.
