The Luminescence of Tungsten: Soul of Light in Photographic Lamp 9

When tungsten lamps illuminated film-era studios, their soft, warm glow painted delicate textures and plump three-dimensional effects across surfaces like an artist’s brush. This radiance originated from a single resilient tungsten wire within the photographic lamp. In early photography, carbon-filament lamps briefly flickered to life, yet their fragility and dimness left photographers anxiously waiting in faint light. In 1909, Dr. Coolidge succeeded in drawing tungsten into fine filaments. With its extraordinary melting point of 3422°C, tungsten finally claimed its throne…

Differences Between Tungsten Disulfide and Tungsten Diselenide 15

Tungsten disulfide and tungsten diselenide are typical compounds of the rare metal tungsten, both formed by combining the transition metal element tungsten with chalcogen elements (oxygen group elements). Both exhibit excellent physical, chemical, and thermal properties and are widely used in the optoelectronic field. However, there are significant differences between them in terms of specific concepts, properties, and applications. These differences stem from the distinct characteristics of sulfur and selenium, the chalcogen elements involved, which in turn lead to variations…
