Dominant ultraviolet-blue photoluminescence of ZnO embedded into synthetic opal

Equations for filling factor estimation in opal matrix. Addendum to “Deep level emission of ZnO nanoparticles deposited inside UV opal”, [Opt. Commun. 259 (1) (2006) 378–384]

“…Despite of the fact that such sample does not exhibit the blue-shift with increasing angle, the influence of photonic band-gap (PBG) in opal with disordered FCC structure is possible to observe conclusively either in evolution of photoluminescence arising due to gradual increase of the filling factor or in temperature-dependent photoluminescence 16 .…”

“…While perfectly ordered opal matrix may find its applications in various light emitting devices 3, 4 , imperfectly assembled and/or amorphous opal with embedded luminescent nanoparticles might be useful for applications in full-color displays 16 . Nanoparticles infiltrated in interglobular spaces can considerably alter the optical properties of opal matrix.…”

The role of saturable absorbers thickness in the Q-switching of the erbium-doped fiber laser

“…Researchers from all over the world have reported a range of approaches in the literature for depositing ZnO thin films by manipulating key parameters and employing diverse methodologies. Multiple techniques including physical vapor deposition, chemical vapor deposition, chemical solution deposition, molecular beam epitaxy [20][21][22][23], sputtering [24], spray pyrolysis [25][26][27], electrodeposition [28,29], and sol-gel technique [30][31][32][33] have been used to fabricate thin films. Compared to other approaches, pulsed laser deposition (PLD) has various benefits, including the ability to create high-quality thin films at low temperatures, ease and low cost of manufacturing multi-layers compared to other processes, and the ability to fabricate uniform thin films.…”

Preparation of Porous ZnO Film by Zinc Oxalate Recurrence Method

“…Zinc oxide is an unique material that exhibits semiconducting and piezoelectric dual properties, which is widely applied in industry for many purposes such as optoelectronics, sensors, transducers and biomedical science [1,2], antireflection coatings, transparent electrodes in solar cell, laser and surface acoustic wave devises, etc [3][4][5]. Recently, Abrarov embedded ZnO into the synthetic opal by using the spray pyrolysis method and it exhibited a broadened dominant excitonic band edge emission and rapidly decreasing deep level emission with decreasing temperature in contrast to ZnO powder [6,7]. Especially, ZnO-infiltrated photonic crystal may be promising in the fabrication of efficient bright phosphors for the full-color displays [8].…”
