Tiub Geissler
Tiub Geissler adalah tabung pelepasan gas awal yang digunakan untuk menunjukkan prinsip-prinsip pelepasan cahaya elektrik. Tiub ini dicipta oleh ahli fizik Jerman dan pembuat kaca Heinrich Geissler pada tahun 1857. Ia terdiri daripada silinder kaca yang diselaraskan sebahagian daripada pelbagai bentuk dengan elektrod logam di setiap hujung, yang mengandungi gas jarang seperti neon, argon, atau udara; wap raksa atau cecair konduktif lain; atau mineral atau logam boleh terbentuk, seperti natrium. Apabila voltan tinggi digunakan antara elektrod, arus elektrik mengalir melalui tiub. Elektronik sekarang melepaskan elektron daripada molekul gas, mewujudkan ion, dan apabila elektron bergabung dengan ion, gas memancarkan cahaya dengan pendarfluor. Warna cahaya yang dipancarkan adalah ciri bahan dalam tiub, dan banyak warna dan kesan pencahayaan yang boleh dicapai. Lampu pelepasan gas pertama, tiub Geissler adalah barang-barang baru, dibuat dalam pelbagai bentuk seni dan warna untuk menunjukkan sains baru elektrik. Pada awal abad ke-20, teknologi ini dikomersialkan dan berkembang menjadi pencahayaan neon.
Definisi Geissler tube dalam kamus Corsica
Takrif tiub Geissler dalam kamus adalah sebuah kapal kaca atau kuarsa, biasanya mempunyai dua mentol yang mengandungi elektrod yang dipisahkan oleh tiub kapilari, untuk mengekalkan pelepasan elektrik dalam gas bertekanan rendah sebagai sumber cahaya yang boleh dilihat atau ultraviolet untuk spektroskopi.
