Photo-induced charge transfer in Prussian blue analogues as detected by photoacoustic spectroscopy
(ScienceDirect, 2013-01-16)
Adipogenic differentiation of murine bone marrow mesenchymal stem cells induced by visible light via photo- induced biomodulation
(2019-03-01)
Background: Bone marrow mesenchymal stem cells (BM-MSCs) are undifferentiated cells that can proliferate and differentiate into specialized cells for tissue self-repair. Low-level laser (LLL) can induce biomodulatory effects ...
Photo-induced birefringence and surface ripples structures in As-S-Ag chalcogenide thin-films
(2019-09-01)
Photo-induced phenomena are investigated in new metastable Agx(As20S80)100-x chalcogenide thin-films prepared by the co-evaporation technique. Under irradiation using an Ar laser at 488 nm, periodic ripples structures ...
Competition between anchoring and reversible photo-induced alignment of a nematic liquid crystal
(Springer, 2003-01-01)
We investigated the alignment induced on a nematic liquid crystal (LC) by a photo-aligned polymer film with azo-dye side groups. The orientation of the LC molecules can be manipulated in a reversible manner by irradiating ...

Molecular engineering strategies to control photo-induced birefringence and surface-relief gratings on layer-by-layer films from an azopolymer
(Elsevier B.V., 2004-04-01)
The interactions governing adsorption of layer-by-layer (LBL) films from an azopolymer, PS-119(R), and poly(allylamine hydrochloride) (PAH) have been controlled by modifying the pH of the solutions used to form the films. ...
Photo-induced effects in Ge25Ga10S65 glasses studied by XPS and XAS
(Elsevier B.V., 2005-05-12)
The present paper focuses on the structural, electronic, and compositional properties of Ge25Ga10S65 glasses before and after UV illumination in air using X-ray photoelectron spectroscopy (XPS) and X-ray absorption ...
Investigation of temperature influence on photo-induced conductivity in n-type AlxGa1-xAs
(1998-12-01)
We present conductance as function of temperature (G×T) under influence of monochromatic light in the range 0.5-1.5 μm for direct as well as indirect bandgap n-type AlxGa1-xAs. Results obtained below 60 K in indirect bandgap ...
