इंग्रजी मध्ये PHOSPHORESCENCE म्हणजे काय?
फॉस्प्रोरेसन्स
फॉस्प्रेसीसेंस एक विशेष प्रकारचा प्रतिजैविकांशी संबंधित फोटोोल्युमिनेसिसन्स आहे. फ्लूरोरेसँन्सच्या विपरीत, फॉस्फोरोसेंट सामग्री लगेच शोषून घेतलेली विकिरण सोडत नाही. पुन्हा उत्सर्जन कमी झाल्यास, "क्वांटम यांत्रिकी" मध्ये ऊर्जा राज्य संक्रमणे सह "निषिद्ध" ऊर्जा संबंधित आहे. काही संक्रमणे मध्ये या संक्रमणे अतिशय मंदपणे होत असल्याने, मूळ उत्तेजना नंतर अवशोषित किरणोत्सर्गास काही तीव्रतेच्या तीव्रतेस पुन्हा उत्सर्जित केले जाऊ शकते. फॉस्फोरसेंट साहित्याची सामान्यपणे पाहिलेली उदाहरणे म्हणजे उजेड-इन-डार्क खेळपट्टी, पेंट आणि घड्याळ डायल्स ज्यात चमकदार प्रकाशासह काही काळ वाचता येते जसे की सामान्य वाचन किंवा रुम लाइट. विशेषत: चमकणारे मग एका गडद खोलीत मिनिटांच्या आत हळू हळू फिकट होते. फॉस्फोरसेंट साहित्याचा अभ्यास 18 9 6 मध्ये रेडियोधर्मितीच्या शोधात झाला. विचित्र, पांढरा फॉस्फरस प्रत्यक्षात या मालमत्तेचे प्रदर्शन करत नाही, परंतु केमिल्युमिनेसिसन्स.
इंग्रजी शब्दकोशातील phosphorescence व्याख्या
डिक्शनरीमध्ये फॉस्प्रेसीसन्सची पहिली परिभाषा ही रोखून धरलेली विकिरण निर्मिती झाल्यानंतर कायम राहिलेली प्रतिदीप्ति आहे. फॉस्प्रेसीसेंसची दुसरी परिभाषा म्हणजे एक प्रतिदीप्ति आहे ज्यासाठी उत्तेजित अणूंचा सरासरी आजीवन 10-8 सेकंदापेक्षा जास्त असतो. फॉस्स्फोरसन्स हे फॉस्स्फोरसन्समध्ये उत्सर्जित झालेले प्रकाश आहे.

Principles of Fluorescence Spectroscopy
Luminescence is formally divided into two categories—fluores cence and
phosphorescence—depending on the nature of the excited state. In excited
singlet states, the electron in the excited orbital is paired (by opposite spin) to the
second ...

Photochemistry of Organic Compounds: From Concepts to Practice
Few compounds emit substantial phosphorescence in solution; biacetyl is a well-
known exception to the rule. Phosphorescence lifetimes tend to be much longer (
milliseconds) than fluorescencelifetimes (nanoseconds;seeSection2.1.1) ...

Handbook of Pharmaceutical Analysis
The return of molecules from the lowest triplet state to the ground state may be
accompanied by a long-duration light emission known as phosphorescence.
Phosphorescence, like fluorescence, is most often observed in molecules having
rigid ...

The mechanism for long persistent phosphorescence can be explained in terms
of a simplified three-level diagram including a ground state, an excited state, and
a metastable trapping state for the active electron (Figure 7). Phosphorescence ...
