TY - JOUR AU - Baghel, R N AU - Parganiha, S AU - Chandra, B P PY - 2012/10/19 Y2 - 2025/09/23 TI - Hypervelocity impact induced mechanoluminescence of phosphors JF - Recent Research in Science and Technology JA - RRST VL - 4 IS - 8 SE - Articles DO - UR - https://www.updatepublishing.com/journal/index.php/rrst/article/view/952 SP - AB - <p class="MsoNormal" style="text-align: justify;">Phosphors are materials doped with one or more impurities that give cold light emission when excited. When a high velocity projectile strikes the backside of a metal plate whose front side is coated with phosphor, then the light emission takes place from the phosphor. ZnS:Mn is an important phosphor which has many applications. It is observed that, when a projectile moving with a hypervelocity makes an impact on to the metal plate coated with ZnS:Mn phosphors, then<span>&nbsp; </span>intense mechanoluminescence (ML )is produced.. The present paper reports the kinetics of ML induced by hypervelocity impact on ZnS:Mn phosphors ,whereby a good agreement is found between the experimental and theoretical results.&nbsp;</p> ER -
