Influence of the composition of (TlGaS2)1–х(TlInSe2)x solid solutions on their physical properties

open access: yesSemiconductor Physics, Quantum Electronics & Optoelectronics, 2017
The single crystals of (TlGaS2)1–х(TlInSe2)х (х = 0…0.5) solid solutions have been grown up. The photoelectric, X-ray dosimetric, dielectric and optical characteristics of the (TlGaS2)1-х(TlInSe2)х solid solutions with various compositions have been ...

High prevalence of self-reported photophobia in adult ADHD

open access: yesFrontiers in Neurology, 2014
Many adult outpatients with ADHD report an oversensitivity to light. We explored the link between ADHD and photophobia in an online survey (N=494). Self-reported photophobia was prevalent in 69% of respondents with, and in 28% of respondents without ...

Photography’s Other Sensitivities

open access: yesMedia Theory
This article sets out to challenge the idea of photography as a medium that deals purely in the visible. Taking the example of the mid-twentieth-century British photography industry, this article considers photographic sensitivity as part of a sensory ...

One photon and two photon process in photo-decomposition of germanium oxygen deficient centres

open access: yes, 1997
There has been much debate on the fundamental mechanism of photosensitivity in germanium-doped silica optical fibres. The importance of the effect, which was discovered by K.O.Hill in 1978, has been well demonstrated by the still rapidly increasing ...

Real-World Safety of Oral Isotretinoin in Patients During Sunny Months: Retrospective Cohort Study

open access: yesDermatology Practical & Conceptual
Introduction: There is a widespread clinical practice of avoiding oral isotretinoin administration during the sunny season due to its purported photosensitizing effect. However, this approach is not supported by solid evidence.

Pediatric photosensitivity [PDF]

open access: yesPhotodermatology, Photoimmunology & Photomedicine, 2012
SummaryPhotosensitivity is a rarely encountered problem in the pediatric population. It may be caused by a diverse group of primary, idiopathic photosensitivity conditions, or may reflect photoexacerbation of an existing dermatosis. In addition, there are several genodermatoses, metabolic disorders, and connective tissue disorders that can present with

The photosensitivity of a-Si:H/P+Pc-Si heterojunction

open access: yes, 1986
We have investigated the photosensitivity of the a-Si:H/P+Pc-Si heterojunction. It has been found that the capacitance of a-Si:H/P+Pc-Si heterojunction have an excellent photosensitivity, and potential application as a photosensitive capacitors.
