अंग्रेज़ी में QUANTUM EFFICIENCY का क्या अर्थ होता है?
क्वांटम दक्षता
शब्द क्वांटम दक्षता एकात्मक डिवाइस के कनवर्टेड इलेक्ट्रॉन अनुपात में घटना फोटॉन पर लागू हो सकती है या यह मैग्नेटिक टनल जंक्शन के टीएमआर प्रभाव को संदर्भित कर सकता है। चार्ज-युग्मित डिवाइस में यह डिवाइस की फोटोरैक्टिव सतह को मारने वाले फोटॉन्स का प्रतिशत है जो चार्ज वाहक का उत्पादन करता है। इसे प्रति फोटोन या प्रति अमोन प्रति वोल्ट में मापा जाता है I QE प्रकाश की डिवाइस के विद्युत संवेदनशीलता का माप है चूंकि एक फोटान की ऊर्जा अपने तरंग दैर्ध्य के लिए विपरीत रूप से आनुपातिक है, क्यूई को अक्सर प्रत्येक फोटान ऊर्जा स्तर पर एक डिवाइस की दक्षता को चिह्नित करने के लिए कई तरंग दैर्ध्यों की श्रेणी में मापा जाता है। बैंड अंतर के नीचे ऊर्जा वाले फोटॉनों के लिए QE शून्य है। फोटोग्राफिक फिल्म में आमतौर पर 10% से कम QE होता है, जबकि सीसीडी के पास कुछ तरंग दैर्ध्य पर 90% से अधिक का QE हो सकता है।
अंग्रेज़ीशब्दकोश में quantum efficiency की परिभाषा
शब्दकोश में क्वांटम दक्षता की परिभाषा दी गई ऊर्जा की घटना विकिरण के प्रति फोटोकल प्रति फोटॉन द्वारा जारी इलेक्ट्रॉनों की संख्या है। क्वांटम दक्षता की अन्य परिभाषा एक रासायनिक ऊर्जा की संख्या है जो दी गई ऊर्जा के अवशोषित विकिरण के प्रति फोटोन प्रति प्रतिक्रिया होती है।
